Best Air Purifier For Allergies

For allergy relief you wish to remove the airborne contaminants. Again, this really is the dust, pollen, mold spores, etc..

Up to now 15 hot air purifiers have been analyzed by us. To do this we use a particle counter to observe how nicely the air cleaners create an atmosphere that is clean.

The graph below shows the particle size of many items. The equipment we utilize test particles from the area and the region to the right. So, we can observe every air purification system eliminates particles at different sizes. Best Air Purifier For Allergies

The numbers across the top of the chart show the particle size in microns. A micron is a one millionth of a meter.

Thus we can only see things down to 10 microns in size. Smaller than it and that’s too small to see.

The items smaller than 0.1 microns are good particles or gases.

Therefore, it isn’t surprising that a fantastic allergy air purifier can remove all the particles.

Based on our testing there is nothing that comes near a true HEPA air purifier. The rationale is that the allergy particles are removed from them.

HEPA filters remove from the air than the others. In our HEPA air conditioner page we explain that HEPA utilizes 3 principles to eliminate particles. 1 principle, diffusion captures particles smaller than 0.1 microns.

The other two principles capture particles 0.4 microns and larger.

Taken collectively they eliminate both the small, middle and large size particles.

The weak point for a HEPA filter is at the 0.3 micron size. This is where we quantify HEPA filter performance.

By operation we suggest that the filter efficiency and air flow. Efficiency is the percentage of all particles which are removed from the atmosphere. Air flow is the amount of air that circulates through the air purifier.

To clean out the air from allergens you want a high performance filter. And to transfer a good quantity of air.

It seems simple but it’s not simple to do. The results of the testing reveal a vast range of performance.

That which we find striking is the HEPA standard. To be a genuine HEPA filter it has to remove at least 99.97 percent of particles at 0.3 microns. A number as it is measured at the weakest point.

In the picture above, the black line shows what HEPA filtration is good at removing. Anything to the right of the line is easily filtered using a true HEPA air purification system. Whatever the left could be cleaned using a HEPA air filter but at a lower efficiency.

This means it will likely filter less than 99.97 percent of these airborne pollutants and air pollution particles.

If you want to find out more see our post on MERV evaluations. Here is the rating system for air filters. The very best HEPA filter for home or office use has a MERV 18 rating.

In researching air purifiers we notice exactly the exact same is said by the experts. This includes the very best government agencies who examine asthma and allergies. First and Foremost, the California Air Resources Board. They set a number of the standards.

The crucial thing is to remove the particles. Not to present air pollution like ozone. A true HEPA filter assesses all of these boxes.

This kind of air filter is best for allergy relief to provide you the atmosphere you’re looking for. Other kinds of filters such as those used in a heating system or HVAC filters will not remove and have a much lower efficacy.

To enjoy the benefits of cleaner air in the allergy air purifier there are three points that are key.

Opt for a high efficiency HEPA filter to catch the particles
Verify the HEPA air cleaner has air flow
Reasonable noise level

A high efficiency air filter may remove the pollen and dust pollen including dust mites.

More to the point, it is going to capture the small particles that are airborne. This is important because the particles that are small cause you the most trouble.

Why is this?

In the air longer because the smaller particles suspend. It is in you will breathe what.

The items fall into the floor. It’s crazy that tiny particles can remain suspended in the atmosphere for hours. They can float for days if quite small. That is the reason why all homes have cats dander, even in the event that you don’t own a cat.

So, in deciding upon the best air purifier it is important to remove the smallest particles. However, more is required to clean your space.

You should have good air flow. First and foremost you want air flow that is robust and a wonderful filter.

Air circulation through an air filtration process is referred to as the CADR. The CADR rating stands for Clean Air Delivery Rate. In other words, how much clean air is coming out of this air cleaner.

A higher Clean Air Delivery Rate means atmosphere . You are going to want to acquire at least 2 based on the severity of your allergies or asthma. You can find out more about the CADR ratings scale.

As an example, state your bedroom is 300 sq ft. This is a tiny math exercise but bear in mind.

If your ceiling is 8 ft high then your area is 2,400 cubic feet (300 x 8).

To clean your room four times per hour then needs 9,600 cubic feet per hour of air flow (2,400 x 4).

The components for the CADR evaluation are in cfm (cubic feet per second). Since there are 60 minutes in an hour we have to split the preceding numbers to convert the room size to CADR.

Thus, for 4 air changes per hour in your 300 sf feet room you need a CADR rating of at least 160 cfm. (9600/60).

We did some testing in space and we discover that 4-5 air changes per hour is needed to keep up a high air quality level. With air mixing in by an open door or the venting system requires that the air filtration system to move a lot of air if you’re an asthma and asthma victim.

If you are trying to find a whole house air purifier you may want to see our article on air purifiers. A large square foot area cans wash up . It depends upon the ft room size of your home or living room.

Finally, the third aspect is to have it be quiet. Or at least a reasonable noise level.

This is how we speed allergy air purifiers. It’s this mixture of three variables that guide our rankings of the best room air purifiers.

Additionally, we include an evaluation for ease of use. This is a preference for us. We know not everybody cares about this. When it’s not helpful ignore this.
