Top 8 Best Air Purifiers for
Allergies and Asthma in 2021

Spring and fall allergies are fairly frequent thanks to pollen and leaf mold, yet if you find that your own individual allergy season continues into the summer and winter, chances are you're facing something other than seasonal allergies. You might also be experiencing environmental or interior allergies due to whatever you can think of, ranging from dust mites and bug feces to mold and pet hair. If this is your situation, you should consider buying an air purifier to enhance the air quality in your home. Before dismissing this as a costly luxury investment, you need to understand that simply overlooking your allergies could result in more serious issues later on.

Why use an air purifier?

One of the insidious things with most allergens is that their particles can be so tiny that we cannot actually see them. For this reason, it's tough to get rid of them entirely when cleaning. It also can be troublesome to determine which particular allergen is triggering your response.

Frequent allergens in a household will include:
  • Mold and mildew
  • Animal hair
  • Dust and house mites
  • Pollen
  • Volatile organic compounds
  • Bugs

Indoor allergens have a tendency to move around and finally get deposited on different kinds of surfaces, like the carpet or the bed covers. Once they become deposited, you are subjected to them whenever you step over the carpet or stretch out on the bed. The settled allergens are emitted back into the air you breathe.

Another thing that can trigger mild responses is the smell. But if you are allergic to peanuts, the scent of the nut or peanut butter is not going to provoke a response. This is because the peanut particles that provoke allergic responses cannot be sufficiently fleeting to be breathed in.

When cooked, however, large particles are emitted that can cause food allergies. But it is not the scent, it is the particles that are emitted.

Allergies may also present as susceptibility to such chemicals like fragrances and cleaning agents. This is generally called chemical sensitivity or multiple chemical sensitivity. Persons with this disorder can suffer a wide number of effects. Among them are feelings of nausea, asthma episodes, migraine headaches, vertigo, as well as even heart palpitations.

An air purifier assists in getting rid of these allergens and triggers before you have the opportunity to inhale them. It may contribute to decreasing the necessity for regular thorough cleansing.

But not all air purifiers are created equally efficient at removing allergens. So, there are a couple of things to pay attention to in finding one that will really help make a distinction for you.

Choice of an air purifier for allergies and asthma

Most of the air purifiers are aimed at allergens, smells, smoke, as well as even mold. Though, just saying allergen elimination may not be sufficient in your particular situation. Below are a couple of key features you need to be aware of:

Genuine HEPA filter

A lot of air purifiers are equipped with a multilayer filtration system. These generally contain a HEPA filter, renowned for trapping nearly all of the pollutants found in the air.

For dedicated use in eliminating airborne allergens, a True HEPA filter is essential.

This filter effectively eliminates up to 99.97 to 99.99 percent of the particles in the air. It traps absolutely everything from respirable dust particles to house mites to animal hair. A proper pre-filter unit is equally critical, as it will trap bigger particles like pollen, hair, and dirt.

Activated carbon or activated charcoal filter

If you find that your allergies or asthma are exacerbated by specific smells, an activated charcoal filter is essential. This filter soaks up smells like smoke, cooking, and even flavors produced by chemical cleaners.

Volatile organic compounds are home contaminants present in popular domestic cleaning products, sprays, and other products. These may also trigger asthmatic and allergic responses. Charcoal filters will also soak up VOCs and eliminate them from your surroundings.

Refrain from using ionizers

Certain air purifiers are known as ionic air cleaners or ionizers. They are usually more affordable than air purifiers.

The ionizers use power to form negative ions that are emitted into the air. These negative ions connect with positive ions, like dust. As the two connect, they get too heavy to stay floating in the air and drop to the next nearest surface.

You may think that the air purifier gets rid of them before they reach the ground, but this is actually not always the truth. Once the particulates grow too heavy to levitate, the air purifier is not going to have the ability to draw them in.

Now there is much talk around the issue of whether or not ionizers are able to assist in the fight against allergens. But the problem with ionizers is that they trap allergens in the air, just like dust. Once the heavy particles fall to the floor, dust and allergens get stuck to sofas, chairs, bedding, and floors that need extra cleaning.

Even worse, this can cause additional allergic or asthmatic reactions if you don't get rid of them by cleaning.
