Air Purifiers: Caveat Emptor

If you are in the market for an air purifier, then you have probably noticed that deals and discounts are less common than they are with most other home appliances. The main reason for this is that air purifier manufacturers do not generally introduce new models or make significant changes each year. Other appliance manufacturers typically release yearly revamps and require liquidation in order to make room for the new stock. When you do come across an air purifier that is deeply discounted, then you will definitely want to take a deeper look into why the price is so low. Here are some important factors to consider when shopping for an air purifier:

There Is No Industry Regulation

In the U.S., there are no official standards for the air purification industry. The ones that do exist are established by the industry itself, and no company is obligated to live up to them. You will sometimes come across ratings like CADR, which stands for clean air delivery rate. CADR is a metric established by a trade association, and while it is viable information in context, it does not apply to all air purifiers and can often be misleading. When researching your options, it is important to recognize the various technologies and be able to separate marketing truth from the actual truth. The best all-purpose solution is a room air purifier with both a HEPA filter and an activated carbon filter.

High-Efficiency Particulate Air (HEPA)

A HEPA filter is the most effective way to filter airborne particles. When shopping for an air purifier, it is important to ensure that you are purchasing true HEPA. Many manufacturers use a substandard filter, and then deceptively market it. For instance, the term HEPA-like is a marketing trick and not actually HEPA at all. A true HEPA filter will trap at least 99.97 percent of all airborne particles down to 0.3 microns in size. Rather than accept the presence of a HEPA label at face value, dig into the specifications and determine how it actually performs. Be wary of any manufacturer that promises real HEPA but sells its product at a price well below the market average. Never settle for a cheap imitation, which will be ineffective at best and counterproductive at worst.

Size Does Matter

Another way that companies try to trick you is by selling small, inexpensive air purifiers and making lofty promises about them. An inexpensive desktop air cleaner may sound like a marvelous idea, but in actuality, such a unit barely has the power and efficiency to clean an area of a few feet thoroughly. Furthermore, small units often employ controversial or ineffective technologies that can often pollute the air as much as or even more so than they clean it.


Ionic air cleaners emit ozone as a byproduct of the filtration process. Ozone is an irritant to the respiratory system and is warned against by the Mayo Clinic, EPA and the American Lung Association. Furthermore, recent studies have demonstrated that ozone has a residual effect, and even small amounts can quickly accumulate to dangerous levels. Another issue with ionization is that it can actually release (redistribute) the pollutants back into the room’s environment, where they can adhere to walls and surfaces. In addition, the increased ions can act as a catalyst and can make immune systems more sensitive to triggers. Many people purchase an air purifier to ensure optimal indoor air quality, so it is imperative not to buy a model that is causing more harm than good. 

Refurbished Air Purifiers

For some home appliances, buying a refurbished unit can be an excellent way to save money. Buying a refurbished air purifier, however, is a lot like buying a used mop. Sure, you can save money, but you’re also introducing someone else’s germs and grime into your living space. Within minutes of running for the first time, an air purifier has already removed dust, pet dander, dust mites, volatile organic compounds (VOC's) and bacteria. The reason why most reputable air purifier companies charge a restocking fee on returns is that they have to discard the entire unit as they would never resell it.

Know the Seller

Choosing the right vendor is nearly almost as important as choosing the manufacturer. Be certain that the HEPA air purifier retailer you buy from is an authorized dealer. The most highly regarded air purifier manufacturers sell their product through authorized dealers like Clean Air Plus in order to ensure that the product is brand new and has not been sitting in a warehouse for a long period of time. It is not unheard of for unauthorized dealers to sell refurbished machines as new units on eBay and Amazon. In addition, buying from an authorized dealer is the only way to be fully protected by the manufacturer warranty.
