How to choose a good air purifier for pet allergies and asthma?
As the most common causes of pet allergies or asthma are from airborne pollutant particles, the more they are reduced, the better life you’re going to have.
This depends mainly on the filtration system of the air purifier that you intend to choose.
And the most efficient type is HEPA filters – the golden standard in this industry because they can trap various airborne particles as small as 0.1 microns. The efficiency rating can be up to 99.97%.
The reason I don’t suggest ionizers (even though they’re also known for highly efficient airborne particle neutralization) is that:
- Negatively charged ions they send out to the air
- Ozone emissions
These two elements are proven by many studies to worsen asthma symptoms, even leading to asthma attacks
About pet allergies, there are many causes:
- Pet’s odor
- Pet’s hair & dander
While the pets’ hair and dander are easily eliminated by HEPA filters, the odor needs a specialized filtration to remove it – activated carbon filter.
For asthma and pet allergy sufferers, this feature is more important.
Why? – might you ask.
Just imagine that you’ve got a room of 100 square feet to purify while the device you’ve just bought just offers a space coverage of 50. This apparently means the air purifier fails to adequately clean your room, making it not only useless but also money wasting.
Therefore, after identifying the room that you want to use the device in, calculate its area (width x length) and compare it to the room coverage on the purifier’s specification table.
These features are just optional for extra convenience:
- Fan speed settings: The more options, the more flexible to adjust and custom to specific air condition, giving more efficiency.
- Automatic operating mode: It features a special sensor to “communicate” the indoor air condition and accordingly, adjust the lights and fan speeds to work on it.
- Remote control: This usually includes a Wi-Fi connection feature to let you track and adjust the device’s functions from distances.
- Night Mode: This allows you to turn off the air purifier and slower the fan speed when you sleep at night

Do air purifiers help allergies and asthma?
Air purifiers exactly can cure asthma symptoms and allergies as they can capture small airborne particles and clean the air.
Do you run an air purifier all day?
Asthma sufferers should run their air purifier 24/7 if you’re always at home because clean air can be re-polluted within 3-5 hours if not re-cleaned by the device.
If you intend to leave your house for a long time, turn it off for energy saving but once coming back home, let it run at the highest mode for at least 1-3 hours depending on your room area. Then, decrease it to medium or low mode.
Can you run an air purifier and humidifier at the same time?
Yes, you can.
It’s because humidifiers and air purifiers do very different things. The humidifiers increase the humid level in the air while the purifiers clean out the pollutants.
Do HEPA filters dry out the air?
No, they don’t
HEPA filters just take a role of remove airborne pollutants to give you only fresh air. It’s designed without any evaporators to dry out the air.
How long does it take an air purifier to clean a room?
It depends on three things:
- Fan speed
- Types of filtration system
- How much polluted air of your room
- Room area
To help you easily get the idea, here is an example.
If you use a true HEPA filter air purifier to clean a 100-feet-square room with the general polluted condition, it will take around 30 minutes to 1 hour to clean it thoroughly.
Air purifiers, they are not only perfect prevention but also a non-medicated cure for your asthma symptom or pet allergies. Choosing a good model, on the other hand, saves lots of filter and energy costs while reducing noise efficiently.
That’s why I hope the list of 6 best air purifiers for pet allergies and asthma above is helpful to you. Thanks for reading!
