home air purifier told you how to Find the Best Air Purifier

With over 300 home air purifier models to select from, choosing the best one for your needs can be overwhelming and time consuming.

Complicating things:

  • Most people have a specific air quality need and units designed as general purpose do not effectively care for specific concerns.
  • Manufacturers use different jargon for the same feature in an effort to make their unit stand out.

 

At Air Purifiers America, we give you just the right amount of information to help you make an informed decision without burdening you with jargon. In fact, we’ve categorized units by specific need to help you quickly understand which units will work for what you care most about. If you have a question as you shop, our product specialists are always available (by phone or chat) to help you choose the best air purifier for you.

 

Our Simple Checklist for choosing the best air purifier:

  1. Know your primary concern (e.g., allergies, dust, chemicals, odor, smoke?)
  2. Know your room size (bedrooms/offices, living rooms/master bedroom, open concept areas)
  3. Know your style and preference (color, texture, shape, size)
  4. Know your budget (less than $250, $250 – $500, over $750)
  5. Know what warranty length you seek (1 year, 10 year, or Lifetime?)

 

Your Primary Concerns:

Air purifiers are designed to solve specific problems and depending on your needs, some units are better suited for a specific need than others. Choose your air purifier by determining:

What Size is Your Room?

Smaller rooms require smaller air purifiers whereas larger open-concept areas require larger units. Larger air purifiers have larger motors and fans to clean large volumes of air. When most air purifier brands speak to coverage area they refer to how much air an air purifier can effectively clean in a specific-sized area. Each of these general room sizes requires a different air purifier to effectively clean your air:

Small Rooms < 400 sq ft
Medium Rooms 400 – 800 sq ft
Large Rooms > 800 sq ft

 

What Are Your Style Preferences?

If you have specific preferences concerning the color, shape, look and feel of your air purifier and how it matches your decor, Air Purifiers America offers three styles of air purifiers (tower, box, and drum units) as well as air purifiers that come in different colors and textures to fit even the most discriminating of tastes.

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

Type Description Effectiveness
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 Precipitator Particles 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 Generator Not 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
