6 Things To Evaluate When Buying Air Purifiers

1. Filter Technology

Perhaps this is the most important factor to look into when choosing an air purifier. There are a few filter technologies available in the market. Each filter technology is different and it is vital to understand how each of them works.

  • HEPA Technology
  • Activated Carbon Technology
  • UV Technology
  • Negative Ion

HEPA Technology

HEPA or High-Efficiency Particulate Air is considered the most efficient air filter type. These are commonly used in high technology industries that demand high air quality. It does a great job of trapping air contaminants and does not release ozone and hazardous byproducts. HEPA air filter is typically made from fiberglass material allowing it to be 99.97% effective in removing particles with a size of 0.3 microns. It does best in fighting common indoor allergens.

In order to trap air pollutants, HEPA air filters require fans. This fan attached to it will absorb the contaminated air and the filter will trap the pollutants during that process. Although air particles as small as 0.01 microns can be this filter’s weakness. Examples of such air particles with this size are chemical fumes, volatile organic compounds, viruses, germs, and cigarette smoke.

Activated Carbon Technology

The activated carbon air filter can remove gases, fumes, and cigarette smoke that the HEPA filter missed. This type of filter technology has small pores between each carbon atoms. These pores can trap the air pollutants as small as 0.01 microns. Carbon Technology uses materials such as wood, coconut shells, and coal. The carbon granules and carbon fibers used in these kinds of filters are best at trapping gases and fumes.

Take note that once these pores that trap the air contaminants can be filled and once that happened, the filter will not be as effective as it once was.

UV Technology

This technology is excellent at killing bacterias and viruses which the previously mentioned air filters are not the best at. This type of air purifier uses a UV lamp. This UV lamp will radiate ultraviolet rays that will cause damage to the microorganisms and will eventually kill them. This technology gives the filter its best trait in preventing the spread of illnesses and diseases.

This means that if your problems are common indoor allergens, chemical fumes, and gas, this kind of air purifier might not be what you are looking for.

Negative Ion

Technically, negative ions are simply oxygen atoms that have gained an electron. This electron magnetically attracts air pollutants such as pollen and dust. It neutralizes fumes, smoke, viruses, and bacteria. One thing to consider is that it does not deal with bad odors.

2. Service Level

A company that provides good customer service to its customers can always help us be certain that we are buying from the right people. The product should be as good as the company. And yes, an air purifier should not even need many maintenance calls to begin with if it’s really good. But most air purifiers should be cleaned when used continuously in a certain amount of time.

3. Pricing

Pricing is a constant concern when purchasing products, and it should be. It is our right to know if the money we are spending is going to a product that is effective and durable.

4. Accountability

Getting the results you want when you purchase something is the most important and it is vital to be certain about it. This is what an air quality indicator is for. It monitors in real-time the quality of the air in your household. If that air purifier is not accountable for improving the air you breathe, then start looking for a new one.

5. Size of the Room

Even if you buy the best-rated air purifier in the market, it will not work at its best if it is not compatible with the space of your room. So measure the size of your room and the specific place where you would place it and compare it to the size of the air purifier options. Brands usually indicate when their product is appropriate to a certain space only. This physical factor should not be overlooked.

6. Brand Name

It is important to look into a brand that cares and truthfully advertises their product. Reputation is important. Check online reviews, ask your friends, and look at the company website. There are plenty of ways to see if a brand and be trusted or not. When making purchase decisions, it is always up to our decision on who and what we consider.


Buying the right air purifier can do so much for your health and safety. At the end of the day, you just have to widen your options and narrow it down by seeing what features you actually need. We have different concerns in our home and that concern will determine what kind of air filter you really need. Just be knowledgeable when browsing through your options and you will make a smart purchase.
