Air purifier popular, choose to pay attention to these 4 indicators

In recent years, the air purifier market demand increased dramatically. In March this year, the formal implementation of new national standard air purifier. The 4 core indicators listed in the new national standard, can make consumers more rational, more intuitive to buy air purifiers. The reporter recently visited the home appliance stores found that many people still do not understand the indicators in the new national standard the significance of the purchase, are often confused.

The air purifier sales hot 

The air purifier sales season in November each year to second years in February. Last month, we store the air purifier sales had exceeded 320 thousand yuan, compared with the same period last year grew by about 10%. Suning Tianyi life appliance sales supervisor Huang Yanfu told reporters, the air purifier sales now account for the store of life general electric 30% sales, the momentum of rapid development.

Every time a small explosion of air pollution, will make the air purifier market ushered in a wave of “outbreak”. “Since 2013, sales of air purifiers showing explosive growth. Especially in 2014, 2015, the average annual growth rate of over the air purifier sales Deputy General Manager 150%. Su ningyun group Limited by Share Ltd in Ningbo area management center Hu Yu told reporters, although just entering the season, but this year he air purifier sales confidence. According to Hu Yu estimates, this year Ningbo air purifier sales reach at least twenty thousand units.

4 indicators to measure product performance

SHARP, Blueair, Olans. ..Today, the market range of air purifier brand many people have no choice. “In fact, no matter what the purification principle, is to detect the air purifier according to the detection method of the same.” Hu Yu told reporters that the measure of an air purifier performance of the 4 core indicators can refer to the new national standard list: clean air volume (hereinafter referred to as Cadr), the cumulative amount of purified (hereinafter referred to as CCM), the purification efficiency and noise.

“Cadr value, clean air volume per unit time through the filter output. In general, the bigger the Cadr value, the purification ability is stronger.” Hu Yu told reporters, usually, the applicable area of clean air available amount multiplied by the coefficient of air purifier (0.07 – 0.12) to estimate. The Cadr value is 400 per hour cubic meters of air purifier for example, its application in the area of 28 square meters to 48 square meters. As for the air purifier to output that can work long, mainly to see the value of CCM. That is to say, the bigger the CCM value, the service life of the screen is longer.

Hu Yu also told reporters that the air purifier mainly relates to particles and formaldehyde two pollutants. If an air purifier is marked with particles of Cadr value, CCM value, Cadr value and marked with formaldehyde, CCM value, indicating that the air purifier can purify particles can also purify formaldehyde.

Purification efficiency and the operation noise of the air purifier, is also an important indicator to measure the performance of the product. “In general, clean energy efficiency rating for air purifier, air purifier is superior to the qualified level.” Hu Yu said that the air purifier is the implementation of noise as low as possible.3 months of the new national standard, the highest air purifier the noise should not exceed 70 dB.

Purchase should be based on their own needs

“After the implementation of new national standards, the core index of air purifier in the packaging or instructions of the conspicuous position marked, consumers should only compare related values, can find a suitable air purifier.” the city Consumer Protection Committee Deputy Secretary General in Leimin told reporters that some business performance in order to more intuitive publicity of air purifier also, the relevant numerical made stickers in the air purifier. An air purifier to determine whether the implementation of the new national standard, standard execution view the product packaging or instructions. If the standard is GB / t18801-2015, is according to the new international standard production.

In addition to the related numerical selection air purifier, consumers can choose according to the different functions of different air purifiers. Young and old groups can choose the air purifier with microorganism removal function, but has the function of air purifiers generally higher prices; if consumers do not want to often replace the filter, can choose CCM value of air purifier is bigger; if consumers use air purifier in a newly renovated room, can choose Cadr value formaldehyde air purifier with formaldehyde high CCM value.

The use of air purifiers, when to replace the filter, is a lot of consumer concerns. The reporter visited found that the current situation of air cleaner production at present most manufacturers can automatically prompt screen. For example, PHILPS air purifier, just change the filter, the air purifier will be displayed on the display of “C7”; when the filter needs to be cleaned, the air purifier will be displayed on the display of “F0”; when the filter needs to be replaced, display the word “A3” is the air purifier on the screen. The current status of air purifier Olans display screen more directly. According to guideintroduction, Olans air purifier filter display the number of days to 0, consumers should replace the filter.

How to buy air purifier? It doesn’t have to be expensive but to choose suitable

A haze into the winter season, masks, air purifiers and other products demand, seems to have become law. And with the heating season, the air quality situation may become more severe. The reporter visited Taiyuan several appliance stores found all kinds of anti haze products ushered in a buying spree.

The influence of air quality, people have taken measures to buy air purification products to deal with. In Taiyuan electrical appliance stores, in order to facilitate the consumers to buy air purifier products are placed in the most prominent position. The new road is located in a home appliance store sales staff told reporters that in recent years, due to the weather, air purifier market is very hot, not only in Taiyuan, many other people in the northern city with purchase intention. “Air purification products for the autumn and winter haze depend more and more intense, dependent on the weather situation is quite obvious.” the sales personnel, recently sold in more than half of small household electrical appliances, air purifier products, some good the brands and models of products are often out of stock, National Day during the purification rate of high net worth of the Gao Jie product sales more than doubled last year.

To reduce pollution, clean air to breathe, anti haze products have become the necessities of daily life of consumers. This year the new national standard in March formally implemented, air purifier products standards become there are rules to follow, the air purification products chaos situation has improved, related products to enter the era of regulation.

However, in the face of the market every kind of products, some consumers are confused at the time of purchase. “When a serious haze days in autumn and winter, my throat is uncomfortable, because it is not good for health, want to buy an air purifier, but to see so many brands, know so much, or don’t know what to do.” Taiyuan “after 50” Ms. Wang Yujing told reporters, according to the purification effect of choice, but many air purifiers hit “high-tech” signs, some marked “formaldehyde removal rate of 99.9%, some marked” Plasmacluster technology “, make a person dazzling, no start.

In this regard, the Shanxi environmental protection industry Wu Hong said that after the introduction of the new national standard air purifier, noise on basic removals, products, energy efficiency and other indicators have made provisions to certain norms of the market. “The new national standard is a qualified line, only to meet the new national standard of products to enter the market now. On the market brand less than before many, so long as in large shopping malls to buy, consumers do not need to worry about quality issues”

For many years engaged in the sales of home appliances industry in Taiyuan Li Yuan suggested that the air purifier type are many, some can sterilization, some in addition to haze, consumers should not blindly buy. Before the purchase, must have a clear purpose, and then targeted to choose their own family products. If the new home repair, you can choose to go to formaldehyde. There are a lot of domestic and imported brands are designed for this. If it is to clean the indoor air, you can choose to clean, good dedusting effect, with the function of sterilization products, many brand products can be intelligent in addition to formaldehyde, haze and pm2.5. “in addition, many doors and windows closed to prevent haze into, in fact does not to prevent air pollution, can reduce the PM2.5 index, but will make the air circulation is not smooth, easy to breed bacteria, and other microorganisms in a confined environment, will cause harm to human health. Therefore, the autumn” Winter haze, the correct method is more important.

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.
