Whole-House Air Purifiers: Efficiency Report

Manufacturers say their newest designs of whole-house air purifiers reduce the amount of ozone that’s in the home through the use of carbon filters, which appears plausible. However, you still should be wary about claims of overall effectiveness.

OLS-K06A

The push for healthier indoor-air quality by Environmental Protection Agency and the green-building movement has fueled the market for whole-house air purifiers in today’s homes. According to market-research group Freedonia, sales of portable and whole-house air purifiers are expected to rise by 4.8 percent annually to $1.7 billion in 2014.

As concerns about the effects of poor indoor-air quality have increased, manufacturers have marketed whole-house air purifiers as capable of doing more than ever before—including helping consumers who suffer from chronic respiratory illnesses, such as allergies and asthma. Although studies indicate that some claims might have merit, other claims are misleading.

In 2009, Food and Drug Administration issued cease-and-desist orders to 10 manufacturers that claimed that their whole-house air purifiers could remove the H1N1 flu virus. FDA’s approval of air purifiers extends only to models that are considered commercial-grade and are approved as a medical device in hospitals and laboratories. Such models may make this virus-killing claim, says Sarah Clark-Lynn of FDA. As of press time, no portable or whole-house air purifier that’s marketed to the consumer can treat, prevent or remove the H1N1 virus, Clark-Lynn says.

CARBON CONCLUSION. When it comes to whole-house air purifiers, the biggest change in the past 3 years is the increase in the number of units that include carbon filtration to address ozone.

The emission of ozone is a particular problem with whole-house electronic air cleaners, which apply an electric charge to trap irritants on plates of filterlike grids. (The other type of whole-house air purifier—media filter cabinets—moves air through a filter that must be replaced every so often.)

Seven manufacturers now have models of both types of whole-house air purifiers that have carbon prefilters and final filters. The use of carbon filters not only removes odors that are left behind from cooking and tobacco smoke, but it also captures ozone (and volatile organic compounds, or VOCs), manufacturers say.

The ozone that’s captured isn’t just the ozone that’s produced by electrically charged rods that are in whole-house air purifiers. The latest whole-house air purifier from Lennox, which is called PureAir and was released in 2012, helps to eliminate the ozone that occurs naturally in highly populated areas and collects in a home, says Kevin Lyons of Lennox. It reduces the ozone that’s produced by electrical motors, cleaning chemicals, home furnishings and automobile emissions in the garage. Lennox says the carbon filters that are in the PureAir reduce ground-level ozone that forms inside of a home by 50 percent. Other manufacturers make similar claims but without a specific reduction figure.

Models that have carbon filters start at $239, compared with $130 for similar models that have a only standard mesh filter. Based on our conversations with manufacturers, we believe that increasingly more models will include carbon filters in the next 3 years.

No test data confirm the effectiveness of ozone removal by a whole-house air purifier, but Brett Dillon, who owns IBS Advisors, which is an energy-efficiency consulting company, tells us that whole-house air purifiers that are fitted with carbon filters can be effective at clearing ozone and VOCs. However, he points out that the efficiency of carbon filters decreases over time. Also, depending on the type of filter that’s used, areas that have high humidity also might decrease the effectiveness of carbon filters.

Three experts tell Consumers Digest that a big part of a whole-house air purifier’s effectiveness is how well that it’s maintained. The introduction of carbon filters made us wonder whether this type of filter shortened the recommended interval in which you should replace the filter. Happily, that doesn’t appear to be the case. Manufacturers say carbon filters should be changed every 3 months—the same as standard filters. Unfortunately, you should get ready to reach for your wallet anyway. The cost of a replacement carbon filter ranges from $35 to $60. A standard filter costs about $60 for a year’s supply, or $15 every 3 months.

How to Buy an Air Purifier for your home

We’re glad you asked! After being introduced to air purifier technology you might wonder, “This is great, but what does my home air purifier actually do?” It’s a great question; understanding what air purifiers do is important for picking the right one.

To Put it Simply: Air Purifiers Clean the Air

Air purifiers clean your air by passing it through a filtering process that is targeted at removing one or more types of pollutants—dust, allergens, odors, chemicals, and so on.

What the best air purifier has

  • HEPA filtration. HEPA filtration is regarded by experts as the most effective type of filtration for removing allergens and small particles from the air. Other filters are designed to mimic this effectiveness, but few achieve the ability to remove particles down to 0.1 microns in size or smaller.
  • High maximum air-exchange rate. Maximum air-exchange rate refers to the amount of air an air cleaner is capable of passing through its system in a minute. Air purifiers with higher maximum air-exchange rates will clean the air faster than those with lower rates.
  • Filter-change alert. Many air purifiers come with a counter to let you know when it’s time to change the filter. Some operate on a daily-countdown basis, while others actually base this information on the state of the filter.
  • Dust sensor or air-quality monitor. A few air purifiers have automatic sensors to detect how polluted the air is, with the ability to adjust the purifier’s cleaning speed accordingly without manual intervention. This, of course, provides users with less precise control over energy consumption and noise levels, but it’s a useful feature if you’ll be using an air purifier in a non-occupied space.
  • Several fan speeds. Most air purifiers have multiple fan speeds, which adjust the speed at which the air is cycled through the unit. There’s a direct correlation between higher fan speeds and more noise, however.
  • Large capacity. If you need an air purifier for a small space, more affordable options are practical. But for larger rooms, you’ll need to purchase a more expensive model capable of handling more square footage.
  • Reasonable cost of ownership. Most air purifiers have long-life filters that must be replaced every three to five years. Some models have more than one filter, while others come with a permanent filter meant to be vacuumed periodically instead of replaced. The more frequently you have to replace the filter, the more it will cost you over time.
  • No or very low ozone. Experts say that ozone is effective in neutralizing odors and chemical gases. They also say that this is a classic case where the cure is worse than the disease as high-levels of ozone can be toxic. If you opt for an electronic air purifier, chose a design that emits low or, better still, no ozone. Skip ozone generators sold as air cleaners altogether.

Know before you go

Do you want a whole-house or room air purifier? Experts say that a room air purifier might not be necessary for most individuals. Some owners say they’ve experienced significant relief from allergy symptoms with the use of a $25 furnace filter that works with an existing household unit.

Do you have severe allergy or asthma symptoms? Owners and experts agree that for individuals suffering from severe allergy or asthma symptoms, the investment in top-of-the-line air purifiers is worth it. But if you suffer from only mild symptoms or simply want to reduce smoke or pet dander in your home, a more affordable model can do the trick.

How much space do you have? Air purifiers can be heavy and bulky, with some requiring a few feet of clearance on all sides. Be sure to measure your available space and allow for all space considerations before you buy.

What room will you use an air purifier in? If you’re planning to use an air purifier in your bedroom, for instance, you’ll want to choose a model with a noise level that you can tolerate while sleeping. In living spaces, choose an air purifier with adjustable speed settings so you can turn it up to a higher setting when you’re not in the room to be disturbed by the noise.

Value expectations: The dollars and cents of it

Air purifiers aren’t cheap to own. Many cost several hundred dollars up front, and most replacement filters are fairly expensive — some cost as much as $100 for the HEPA filter, with additional costs for prefilters and carbon filters. Some air purifiers require more frequent filter replacements, which adds to the cost over time. Owners suggest purchasing multiple filter packs online to save money. For those suffering from severe allergies or asthma, the cost is often worth it, and you may be able to purchase it with FSA funds with the proper documentation from your medical professional. Others should try more affordable options, such as furnace filters, which cost significantly less and can be just as effective for most people. While there aren’t a lot of complaints about malfunctioning air purifiers, many models offer warranties of five years for peace of mind. Also, keep in mind that if you can hunt down and eliminate sources of allergens and odors, you might be able to do without an air purifier altogether.

Home air purifier:why use hepa filter?

Guangzhou Olansi has conducted testing and research on several models of home air purifiers and filters, using a specialty laser particle counter to measure the percentage of particles removed from the air. Here are the key fact you need to know about HEPA technology and its use in air purifier and HVAC filters.

Why HEPA?

High-Efficiency Particulate Air (HEPA) Filters are proven to be the most trusted filter technology on the market. The key to HEPA Filters is its tightly woven composition, making them an effective and safe solution to remove airborne particles that can aggravate:

  • Allergies
  • Athma attacks
  • Chemical sensitivity
  • Settling dust
  • Mold growth
  • Pet-related allergies and odor
  • Smoke odor
  • Illnesses linked to viruses & bacteria
  • Long term respiratory health problems

    How does HEPA work?

    HEPA Material

    HEPA is a flat, pleated sheet composed of millions of microscopic fiberglass threads, forming a complex maze which traps airborne particles.

    Because particles 0.3 microns are the weakest point of the filter’s performance, a filter is only classified as HEPA if it removes 99.97% of particles that are 0.3 microns.

     

    Three types of capture

    Interception

    As particles flow by, they are attracted and stick to nearby HEPA filter fibers.

    Impaction

    Air flows smoothly around filter fibers, but particles collide and get embedded.

    Diffusion

    Microscopic particles move erratically, increasing the likelihood of being captured by interception or impaction.

    How does HEPA compare to HVAC filtration?

    HEPA filters have the highest level of filtering available. Most home HVAC systems are not designed to handle the strain of the high resistance filtering of a HEPA filter, so an HVAC filter with a tight weave may reduce air flow and ultimately lower air quality. HVAC filters come in different MERV ratings,but even the most efficient MERV-rated HVAC filter is less efficient than an HEPA air purifier. If HEPA filtration is required, we recommend an air purifier.

Why does indoor air quality matter?

The U.S. Environmental Protection Agency (EPA) now lists indoor air pollution among the top five environmental health risks that the U.S population currently faces, and warns that your indoor air is, on average, 2 to 5x more polluted than outdoor air. Since you and your family spend up to 90% of your time indoors, removing particles like dust, chemical and and mold particles with an air purifier can relieve your body of a major stress.

When airborne particles are inhaled, they can damage your lungs and cardiovascular system—the extent and severity of damage is directly related to particle size, as well as length and degree of exposure. Anyone with asthma knows that the outdoor air quality can have a big impact on breathing. But even if you don’t have asthma, you’re probably familiar with allergies, sleep apnea, lung disease or other health concerns related to air quality. Air pollution is particularly dangerous for children, people with asthma and other lung diseases, people over 65, people working or exercising outdoors, anyone who has diabetes, cardiovascular disease, high blood pressure, or who has suffered a heart attack or stroke.

Indoor air commonly contains microscopic particles made of:

  • dust
  • chemical fumes
  • gases
  • smoke
  • skin flakes
  • mold
  • roach excrement
  • pollen
  • animal dander

Exposure to poor air quality can lead to:

  • Allergies
  • Asthma attacks
  • COPD
  • MCS
  • Lung Disease

How to Protect Yourself

Airborne particles vary in size. Depending on which of these particles are causing aggravation, there is a home air purifier that performs to remove these particles from the air. Air purifier filters with the HEPA classification capture 99.97% of particles that are 0.3 microns and will target most of the contaminants shown in the shaded region below. For contaminants outside the shaded region, including smoke, smog, chemicals, and viruses, specialty air purifiers or filters are designed with specific technology to target those concerns.

What is an air purifier?

All home air purifiers are designed to help eliminate free flowing particles in the air. Although these particles are not visible to the human eye, they can trigger health problems like allergies, asthma, chemical sensitivity, headaches, and fatigue.

Air purifiers may be filter or filterless, with filterless air purifiers typically requiring less maintenance but also providing less effective filtration. Types of filterless air purifiers include electrostatic air purifiers and ionizers.

Air purifiers that use filters typically work by using a fan to pull air through a filter which is designed to capture airborne particles. The effectiveness of the air purifier depends on both the strength of the fan and the quality of the filter. The most effective filter material is HEPA (High-Efficiency Particulate Air), which removes 99.97% of particles that are 0.3 microns or larger. Complimentary technology used in the filter or unit may target specific airborne particles such as smoke, mold, or odor.

Types of Air Purifier

TypeDescriptionEffectiveness
HEPA (High-Efficiency Particulate Air)High efficiency HEPA air purifiers effectively capture airborne particles. The percent of particles captured is the highest of any air purification technology available.

High

Removes up to 99.97% of particles like dust, pollen, pet dander, mold spores and more.

Electrostatic PrecipitatorParticles are charged and then stick to oppositely charged metal plates within the air purifier.

Minimal

Does a poor job at circulating air. Requires frequent cleaning of the plates to maintain efficiency.

Ozone GeneratorNot safe and effective at removing pollutants. By design, they produce ozone, a lung irritant that can cause adverse health effects.

Harmful

Does not remove particles in the air. Ozone worsens air quality and can cause damage to lungs when inhaled.

Complementary Technology

Activated Carbon

Effective at removing unpleasant odors, gases, and chemicals in the air. Particles become attracted to, and then trapped within tiny pores in the activated carbon.

Good for: Odor, Gases, Chemicals

UV Light

Kills airborne germs, bacteria and viruses by damaging the bacteria and viruses’ DNA & molecular structure.

Good for: Bacteria, Viruses

Silver Ion Microbial Prevention Filter

Silver-infused filters capture and kill airborne microbes. Silver is naturally anti-bacterial.

Good for: Microbes, Bacteria, Viruses

Ionizer

Helps remove pollen, bacteria, odors, and chemicals in the air. An ionic-only unit provides inadequate filtration. Ionizers are added to HEPA units to improve their performance but should not be used as the sole method of filtration.

Good for: Pollen, Bacteria, Odor, Chemicals

Photo-Catalytic Oxidation (PCO)

Destroys gaseous pollutants by converting them into harmless products by the use of UV light and a catalyst (Titanium Oxide).

Good for: Gases

Pre-Filter

Captures large particles (hair, large dust particles) to extend the life of your air purifier filter.

Good for: Hair, Pet Fur, Large dust particles

Molecular Conversion Powder

Destroys tough odors like tobacco smoke at a molecular level, leaving the air smelling fresh and pure.

Good for: Smoke Heavy Odor

Thermodynamic Sterilizing System (TSS)

Destroys 99.9% of living microorganisms and proteins by exposing them to temperatures above 200 C (approx. 400F). Not available in conjunction with HEPA filtration.

Good for: Bacteria, Viruses, Mold

Olansi is a prime manufacturer and supplier of air purifiers and air cleaners

Olansi was founded in 2009 with the pious objective of providing an alternative to Chinese as well as citizens of other countries of breathing fresh air that was completely free from toxic pollutants.

More often than not, the air that people breathe inside their homes or offices or other indoor locations happens to be more polluted in comparison to the air circulating outdoors. Since the indoor living or working areas tend to be demarcated and enclosed and not unbounded as the outdoor zones, these interior premises tend to tend to trap high proportions of mites, pollens, spores, and other microscopic particles that cause a range of health problems the prominent ones being asthma and allergic disorders. In order to trap these unhealthy and invisible particles floating in the air inside homes or offices, a home air purifier comes in handy.

Guangzhou Olansi Air Purifier Manufacturing is a recognized Chinese concern that has been earnestly engaged in manufacturing a range of air purifiers since 3rd March 2009 in its air purifier factory located in GaoSha industrial zone in Guangzhou city.  The company’s wide range of products include air cleaners, air dust purifiers, air allergy purifiers, air purifiers (for asthma), air purifiers for children, air molds purifiers, air odors purifiers, air purifiers for pets, air PM (particulate matter) 2.5 purifiers, ionizer air purifiers, HEPA air purifiers, and so on. Since the establishment of its production unit, Olansi has been able to step up production without compromising on quality. Three years following its foundation, the company had been turning out 1, 20, 000 units of purifiers.

Olansi after entrenching its business within the country started exploring beyond the national borders. The ministry of foreign trade gave the consent to the manufacturer to export its wares to South Asia, North America, South America, Europe, Africa, and Southeast Asia. In order to gain the confidence of its overseas clientele, the company established a R&D center that concentrated on designing an innovative line of China air purifier. At the same time, Olansi also focused on coming up with world-class water purifiers. So as to bring about a greater consistency in the operational system comprising the different stages in the production process, the firm took the decision of creating a suite of ERP (enterprise resource planning) modules in 2014. The R& D center was further refurbished in 2015 with a view to enhance the efficiency of the entire product line.

The company’s 200 employees combined their efforts to produce 3,50,000 home air purifiers in 2015 and the firm is looking forward to transshipping over 5,00,000 units by the end of 2016. There are several practical reasons as to why customers have been steadfastly procuring air cleaners and air purifiers from Olansi on a recurring basis. Of these, the most significant has to be its capability to supply efficient products at immensely modest prices.
