What to Look for in an Air Purifier

There are several factors which will help you determine how effective an air purifier is:

1. HEPA

There are different types of air purifiers such as UV light purifiers and air sterilizers, but HEPA air purifiers are considered to be the gold standard. HEPA is an efficiency standard for air purifiers.

Air purifiers fitted with HEPA filters make the best air purifiers, but can also the most expensive.

They are commonplace these days, and you can find them everywhere from bathrooms to office spaces to hospitals. Medical professionals will often use them to treat or reduce the severity of allergy symptoms.

    HOW EFFECTIVE ARE THEY?

    HEPA filters eliminate a staggering amount of particles from the air — up to 98%. They work by forcing air through their fine mesh to trap harmful airborne particles such as smoke, pollen and dust mites.

2. CADR 

The next important acronym to keep in mind when looking for an air purifier is CADR.

As you can imagine, this refers to how quickly the unit can purify the room’s air.

Each air purifier has three scores that represent the CADR for each of:

  1. Smoke
  2. Pollen
  3. Dust

These scores are measures of rate at which each device can purify smoke, pollen, and dust. Essentially, the higher the CADR, the more powerful the air purifier.

    WHAT IS CONSIDERED A GOOD CADR RATING?

    Well, this will depend on the size of the room you want the air purifier to be in. As a general rule, try to ensure the CADR of the air purifier is at least two thirds of the square footage of the room.

3. AHAM

The last acronym you will need to familiarize yourself with before investing in an air purifier is AHAM.

AHAM certification means it has passed rigorous testing to see how effectively it cleans smoke, dust, and pollen. Basically the AHAM seal of approval is a surefire way of knowing that the air purifier is of high quality. 

Ensure that the air purifier you choose is AHAM certified.  

Frequently Asked Questions About Air Purifiers

  • Do air purifiers get rid of germs?

Yes! Air purifiers are designed to circulate fresh air around a living space, and eliminate unwanted particles such as bacteria, dust, and pollen. So if you were wondering if you should get an air purifier to help fight off unwanted sickness like colds and flu, then you absolutely should!

By controlling the quality of air in your home, you can defend against germs effectively and worry less about catching something on those cold, rainy days when you’re locked up inside.

  • Do air purifiers work for viruses?

Yes and no.

While air purifiers will remove a high percentage of irritants like dust and pollen from the air, viruses are slightly more complicated to eliminate from a living space. Since virus particles are so small, the air purifier will have a hard time filtering it. However, virus particles that are imbued in moisture droplets resulting from someone coughing or sneezing can in fact be caught, and filtered.

So while air purifiers won’t completely remove the threat of viruses spreading inside, they can certainly reduce the risk. One thing to bear in mind here though is that if the filter doesn’t completely clean the particles, the virus can live on the surface of the air purifier for anywhere from several hours to a few days. So if you need to replace your filter, always make sure you clean it off thoroughly first. You will also need a HEPA filter air purifier in order for this to work.

  • Do air purifiers help with bacteria?

Yes, HEPA filter air purifiers can help eliminate unwanted bacteria from your living space with impressive efficiency. You can expect to reduce the amount of bacteria in the air if you have an ultraviolet light air purifier, or photocatalytic air purifier also.

One of the main purposes of any air purifier is to tackle bacteria and reduce the chance that you breathe in something that could potentially prove harmful.

  • What is the best air purifier for germs?

The best air purifier for germs is the Germ Guardian AC9200WCA. This HEPA filter air purifier uses UV light which is proven to be extremely effective at killing off unwanted germs and bacteria in the air. This air purifier features an impressive 300 CADR, a 5 stage filtration process, and has broad coverage making it ideal for bigger spaces.
