What Is a HEPA Filter: 4 Factors to Help You Buy One

September 10th, 2021

HEPA is an abbreviated form of High Efficiency Particulate Air. These are special filters that can capture particles of different sizes in a multi-layered net. Generally, this net is made from tiny fiberglass threads, which are thinner than your hair strands. The beauty of these filters is that they are air-tight and consist of a sheet of fibers sealed in a plastic frame. In this article, we will get a deeper insight into HEPA filters. Read on to find out more.

According to statistics, HEPA filters can trap up to 99.99% of air particles in your indoor air. Therefore, they have the best tripping power as far as your filters are concerned. So, if you are going to purchase an air purifier, we suggest that you consider a few important factors. Some of those factors are described below. Read on to know more.

What Should you Look for in a Good Unit?

Clean-Air Delivery Rate (CADR)

CADR is a measure of the cleaning speed of an air-purifying unit. These units can help purify your indoor air from dust, smoke, and pollen. Ideally, the CADR rating of the unit should be between 300 and 350.

Size Guidelines

As for as efficiency is concerned, we suggest that you go for a model that can clean the air in your room. In other words, if you have a small room, you can manage with the small unit. On the other hand, if you have a spacious room, a smaller unit won’t do the job. A small unit will continue to work for several hours without giving great results.

AHAM

AHAM refers to the Association of Home Appliance Manufacturers. This standard is a sign of the safety, performance, and efficiency of your domestic appliances, such as air purifiers. Actually, if you look for this standard, it will make it easier for you to make your buying process simpler.

The majority of air purifiers out there have this certificate. Therefore, you can check the CADR rating and other guidelines to make sure you get the best unit.

It is a great idea to invest in an air purifier that is powered by a true HEPA filter. The good news is that HEPA filters are the best choice as far as eliminating allergens and filtering dust particles is concerned.

According to experts, this type of air purifier can filter a minimum of 99.9% of these particles. The size of these particles is 0.3-micron diameter. Since new pollutants continue to become part of your indoor air, we cannot give you an exact figure of how accurate these air purifiers can be.

Long story short, if you are looking to purchase the best air purifier to ensure you and your family is protected against air pollutants, then we suggest that you consider these guidelines. With these guidelines on your mind, you will be more likely to purchase a unit without making some common mistakes.
