But, finding the right one to combat your allergies can be a nightmare. There are a lot of great air filters out there, like A LOT. Sort of a mind-numbing amount of options. But don’t worry, we have compiled a list of the best air purifiers that can see you through even the toughest allergy season.

There are a few considerations to look at when thinking about air purifiers that can help with allergies. Most of all, Allergists and the CDC agree that finding an air purifier that has a HEPA (high-efficiency particulate air) filter is the best choice. You should also consider price, specificity, and design. Below are our rankings for the best of the best.

At the top of our list is the Conway AP-1512HH Mighty, an air purifier that lives up to its name. It does an excellent job of filtering pollutants like smoke, pet dander, and dust, and offers meaningful protection against airborne viruses. The four-stage filtration process is designed to capture 99.97% of particles. It also includes a HEPA filter that is guaranteed for up to one year.

Due to the price difference and impressive feature set, we ultimately decided to put the Conway Mighty at the top of this list. However, the Blueair Blue Pure 211+ came in a close second.

That design feature also makes it great for larger rooms like kitchens or living rooms. It can be placed virtually anywhere in a room and still do a stellar job of filtering irritants.

How To Pick The Best Air Purifier: Step by Step

Hopefully, this list has shed some light on air purifier options. But if you want to find the best air purifier here are some of the key considerations you should be thinking about.


The CDC recommends that anyone who has allergies to pets, mold, dust, or the countless other irritants floating around in the world should buy an air purifier with a HEPA filter. These filters are designed to remove airborne particles as small as .3 microns. This is important to the filtration process for those with allergies due to the buildup of small particle irritants in the air. If you are looking into a new air purifier, make sure it has a HEPA filter.


It may not be the first thing you think about when you start looking for an air purifier, but it is an important category to consider. This will be a fixture in whatever room you decide to put it in, and picking an ugly air purifier can impact the feel of your space. Not to mention the design can impact the operation. For instance, the Blueair Blue Pure 211+ can handle huge rooms thanks to the 360 design. But it would be overkill in a bedroom (most bedrooms anyway.) Same for the Levoit Air Purifier for Home – in a big space with high ceilings you aren’t going to get much performance but in a small room, it is excellent.

Types of Pollutants

Not all air purifiers are built for the same things. There are some that handle dust and pet dander better, some that are better for germs, and some that do extra things like cool as they go. Finding an air purifier that has the right filter for the things you wish to remove is incredibly important to your decision-making process.

What To Know Before Buying an Air Purifier

It is important to remember that upfront cost is not the only thing you need to consider budget-wise. Over the life of your device, you will need to replace the filters, and this can become costly. Air purifiers also pull a decent amount of power and can impact your electricity bill. There are options that are more energy efficient but it is important to remember that the sticker price is only a part of the total cost.
