best medical grade air purifier

According to the Asthma and Allergy Foundation of America, there’s a 40% increased chance of acute asthma attacks in high pollution atmospheres. And having allergies and conditions like asthma is bad enough on its own without polluted air creeping inside our homes.

The solution? Investing in a medical-grade air purifier. So in this post, we’ll help you find the best medical-grade air purifier for yourself and also discuss how and why they can benefit you. Read on!

What Is a Medical-Grade HEPA Filter?

The key to achieving fresh, crisp, and clean air inside your home is to use a medical-grade air purifier.

These devices are mostly used in hospital rooms where there’s a high chance of diseases and contaminants spreading through the air. But what makes this type of purifier so efficient at its job?

The answer lies in the filter. A good air purifier makes use of a HEPA filter, which is the standard set by the US Department of Energy.

A HEPA filter must trap 99.97% of contaminants that are 0.3 microns in size. These include particles such as dust, dust mites, pet dander, mold spores, etc.

Different levels of HEPA filters can trap different sizes of particles in varying percentages. These levels are measured using MERV ratings, and the higher the number, the more efficient your filter is.

For instance, a regular HEPA filter typically used in homes has a MERV rating between 10-12 and can only trap 85-99.50% of 0.1-micron particles.

Medical-grade HEPA filters have MERV ratings of 13 and 14, which is the highest and most efficient level of filtration you can get. They can remove 99.995% of particles measuring as small as 0.1 microns, which includes small bacteria and viruses.

Also, note that HEPA filters are usually called True HEPA because they’re genuinely efficient and approved by the authorities. ‘HEPA Type’ is just a gimmick used by manufacturers to hype up their filters that aren’t as good as they make them seem.

Do You Need a Medical-Grade Air Purifier?

Medical-grade air purifiers are typically used in a hospital, dental office, laboratory, and other commercial and industrial buildings. They prove beneficial in removing harmful particles, such as viruses, bacteria, or allergens from the air so that patients and employees can work in a safe environment.

But there’s no saying you can’t use these inside your homes as well. In fact, we recommend homes with sensitive and allergy-prone individuals to make use of these devices. According to a study, air purifiers can significantly reduce asthma attacks and distress in people with respiratory issues.

Even if you and your house members don’t suffer from any such issues, it’s a good idea to invest in a hospital-grade air purifier anyway. With a crisis like the 2020 global pandemic at our hands, there’s a need for highly efficient air purifiers more than ever.

And the good news is that these devices are readily available for the general public to purchase. Using them will keep you assured that no viruses or allergens will be attacking you inside your home.
