How We Selected Air Purifiers For Allergies
Quality air purifiers clean and deodorize the air in your living and work spaces to help keep you healthy. This can be accomplished with different types of filters and odor-eliminating features. We selected the top air purifiers for allergies for our list by looking for trusted brands with top-rated products. We researched product details, read customer reviews, and checked with an allergist about what to look for.
We chose air purifiers based on the type of filtration they offer and what particles they filter, the square footage they cover, and special features such as automatic mode settings, remote control operation, and automatic air quality detection.
Does An Air Purifier Help With Asthma Symptoms
An air purifier is a device that uses a filter and a fan to trap small particles from the air and recirculate the room with clean air. It can remove many pollutants that trigger allergy symptoms, such as:
There are many different types of air purifiers. High-efficiency particulate air filters are able to capture 99.7% of all particles 0.3 microns or smaller. HEPA filters can be sold on their own or used in other systems, such as your heating, ventilation, and air conditioning system or vacuum cleaner.
Other types of air purifiers include:
- Electrostatic filters, which use a small static charge to attract and trap particles
- Ultraviolet light filters, which kill bacteria and viruses with UV light
- Ionizers/ion generators, which magnetize small particles
When Should I Get A New Purifier
If youre finding that your air isnt as clean as youd like it to be or youve noticed an increase in allergic reactions, you might be thinking about buying a new air purifier. If this is the case, consider checking the filter first and make sure it doesnt need to be replaced.
In most air purifiers, the filter does all the work, so if its not working at its usual capacity, the filter is probably to blame and not the purifier itself. However, if the mechanical hardware like the fan, control panel, or air quality sensors breaks down, youll want to get a new purifier.
In addition, if the air purifier cant keep up in new and larger spaces, consider getting a larger purifier.

We recommend you check out product labels to better understand the devices specifications and read air purifier reviews to find out how the unit rated with testers. Heres an overview of what to look for:
SIZE: Make sure the air purifier youre interested in works for your room size. The devices should give you an indication of whether or not it can handle your space. CADR measures the cubic feet per minute of clean air delivered and the higher the value, the cleaner the air. If youre trying to improve air quality in large rooms, look for a higher CADR.
NOISE: Top quality air purifiers have a series of filters that capture particles and return clean air back into the room which inevitably creates some level of noise. Depending on the model and setting of your unit, sounds can range from a quiet hum to a loud whoosh. If noise is an issue for you, try getting a larger unit itll be effective, efficient and quieter at a lower speed.
FILTER: When youre thinking about , ask these questions:
- What type of filter is it?
- How easy is it to change the filter?
- How often do you have to change it?
- How much do the filters cost?
If possible, get someone to demonstrate replacing the filter so you can see if its difficult. Pro tip look for YouTube videos! Also, do a quick online search to see how much replacement filters cost for that device.

Is An Air Purifier Helpful For Covid
According to the Environmental Protection Agency, an air purifier by itself isnt enough to protect you from contracting COVID-19. However, the EPA website notes, a quality unit can help reduce airborne contaminants including viruses in a home or confined space. In other words, running an air purifier can a good protective measure but it shouldnt be your only one.
Considerations Before Buying A Purifier
In order to buy the air purifier that is the best for your application, you may have to look at more than whether a particular model seems to be a good solution for allergy and asthma sufferers. The technology used is only one part of the equation.
Lets take a few minutes to look at the other factors that will make your buying decision the best that it can be. Remember that, even though we have reviewed several models and have an overall recommendation for what we think is the best, the truly best model is the one that meets your specific needs and usage.
One of the most common specifications youll see when looking for the best air purifiers for allergies and asthma is the coverage area. Thats simply a measure of how big of a room can effectively be purified given the capacity and capability of a particular air purifier model.
Knowing the size of the space you want to purify is pretty important as the amount of coverage area is certainly different from model to model.
So how can you figure out how much coverage area you need to have?
It can be calculated using the simple math formula for an area:
L x W = A
Now, dont freak out and think you have to go back to algebra class. Trust me it wasnt my favorite either! Its actually pretty easy to do!
For a typical rectangular room, take a tape measure and find out the length of the room is. Then measure the width. Multiply the length times the width and youll get the area.

Asthma And Allergies Improvements
Fortunately, both asthma and allergies are conditions that can be controlled and even lessened by taking certain steps. One of these steps is to create a hospitable environment that is free of associated triggers and allergens. Cleaning is an important part of this step, and that includes cleaning the air. Purchasing an air purifier is an effective way to do that. When shopping for an air purifier, youll want to find the best air purifier for asthma and/or allergy sufferers.

An Air Purifier Vs An Air Filter
An air purifier is different than an air filter, which traps pollutants by forcing the air through a filter. While both devices trap and filter out pollutants, only an air purifier sanitizes the air.
An air filter may be part of a heating, ventilation, and air conditioning system or be portable.
Several types of filters may be used in both devices, including:
- pollen from outside
An air purifier can take these triggers out of your home by trapping them in the filter. It works by bringing in air and trapping these small particles, then releasing the clean air. An air purifier also sanitizes the air around it.
However, studies have found mixed or inconclusive results as to whether or not air purifiers help asthma symptoms.
According to the American Society of Heating, Refrigerating, and Air-Conditioning Engineers , air purifiers may be less effective than regular air filters, as they often dont trap particles as well as air filters. If the allergens arent trapped effectively, they may be redistributed on surfaces closer to the purifier.
Other studies have a different opinion. For instance, a 2018 study found that air purifiers are effective for helping to relieve asthma symptoms, especially for children.
According to a 2016 study, air purifiers may be better at getting rid of some allergens, like smoke, but less effective at reducing other allergens, like animal dander.
Overall, how well an air purifier can help with asthma symptoms depends on the:

Dont Store Paint Or Chemicals Indoors
Although you may have your paints, cleaning chemicals, and pesticides stored inside containers, they can still release volatile organic compounds into the air which can irritate your respiratory system. Therefore, its best to keep these products stored outside or in a garage or basement area thats far away from your breathing area. For areas where this is not possible, consider getting one of the best chemical air purifier units to clean the air of these toxins.
Indoor Air Quality Affects Asthma And Allergies
In most homes, the indoor air quality is greatly affected by the type and amount of allergens that are present. Often, the IAQ is as much as five times worse than the air quality outdoors. As a result, inhaling these allergens may trigger asthma attacks in people who suffer from asthma. For allergy sufferers, the release of histamines can result in allergy symptoms that include wheezing, itchy eyes, nose, and throat, post-nasal drip, coughing or sneezing. To combat and eliminate these symptoms, an air purifier for allergy sufferers is extremely useful. The best air purifier for allergies is one that quickly and efficiently removes a significant amount of allergens from the air.

How To Use An Air Purifier For Asthma
Some guidelines for using an air purifier may help you control your asthma symptoms:
- Perform regular maintenance: Washable air filters are often cheaper, but they have to be cleaned regularly. If you dont clean or switch out your air purifier on a regular basis, it can grow mold or reintroduce allergens into the air. This could make your asthma symptoms worse. Aim to replace your filter at least every three months.
- Use a fan:When possible, run your central air system with the fan on. This helps ensure that the air is constantly replaced and your space is well-ventilated.
- Vacuum regularly: You should vacuum with a HEPA vacuum cleaner once or twice a week to reduce your exposure to allergens.
- Monitor your symptoms:To see if your air purifier is helping you manage your asthma, monitor your symptoms with a daily diary. If you take peak flow measurements with a hand-held device, record and monitor these as well. Peak flow measures how air flows from the lungs.
Air Purifiers For Allergies
If you have an allergy, for example a pet or a dust mite allergy, you’re usually allergic to the skin flakes and allergens left behind by dogs, cats, and dust mites. An air purifier helps remove these particles from the air. Air purifiers that relieve allergy complaints have a HEPA filter and clean all the air in a room 3.5 times per hour. As such, an air purifier doesn’t relieve all symptoms, but improves the air quality to reduce the symptoms.

Clean Air Delivery Rate
You also should have good air flow through the air purifier. Most of all you want a great filter and strong air flow.
Air flow through an air filtration system is known as the CADR. The CADR rating stands for Clean Air Delivery Rate. In other words, how much clean air is coming out of the air cleaner.
A higher Clean Air Delivery Rate means more clean air for a given square footage. You will want to get at least 2 to 4 air changes per hour depending upon the severity of your asthma or allergies. You can learn more about the CADR ratings scale.
