How to Choose Air Purifier for Allergies
When you are looking for an air purifier, there are some things that you need to keep in mind. Air purifiers made specifically for allergies are a bit different than regular air purifiers. Factors to consider include:
HEPA Air Purifier
HEPA also known as High-Efficiency Particulate Air Filters is one feature that you should definitely look for in any air purifier. These filters can filter out contaminants from the air up to 99.7%. Moreover, they capture particles that are as small as 0.003 microns.
These help filter out the air and make it more breathable. They treat the air by removing odors caused by smoke, mold, pet dander, and more.
Ionic Air Purifier
This type of air purifier does not use paper filters like the rest. An ionic air purifier emits charged particles that latch on to contaminants and remove them from the air.
The power of an air purifier is another important feature that needs to be considered. Any purifier that you chose should be able to purify the area it is installed in.

Best Air Purifier for Cat Allergies:
What Recent Buyers Report
Users are fascinated by several features of Airthereal PH260 including its near-inaudible operation when on night mode.
The auto-shutoff feature makes operation easy as one doesn't need to monitor the appliance once the timer is set.
However, some users report its inability to properly disinfect an entire 355 sq. ft room size as indicated on the specifications by the manufacturer. It best disinfects indoor air for spaces not more than 255 sq. ft.
Why it Stands Out to Us
The Airthereal PH260 produces minimal ozone as a byproduct and is CARB and ETL-certified hence still good for people with allergies. It is, however, recommended to turn off the UV-light and ionizer most of the time to reduce ozone exposure.
It has impressive three-stage air filtration: pre-filter, true HEPA filter, and an activated carbon filter. First, the pre-filter takes care of large dander and pet hair strands. Next, the HEPA filter removes 99.97% of minute particles, while the activated carbon takes care of unpleasant kitty litter smell and pet odor. The combination keeps air safer to breathe for those with allergies by reducing exposure to particles that trigger allergy symptoms. Additionally, the filters are replaceable after about 6 months of use.
The whisper silent operation with noise levels of as low as 28 dB makes the Airthereal PH260 air purifier ideal for use in baby rooms for children who love playing with cats.
Airthereal PH260 is a high-performance air purifier that would work well for those with allergies and asthma. The molecular sieve, cold catalyst filter, true HEPA filter, and the 3 filtration stages will guarantee up to 99.97% pure air that is free from any cat debris or odors.
The small amounts of ozone produced as a byproduct should not be a cause of worry since the air purifier is CARB, ETL, FCC, and CE-certified.
Common Allergy Triggers in Your Home
It might come as a surprise to most people but very often the things that cause allergies are present in the house. Three of the most common of these triggers are dust mites, mold, and pet dander.
Dust mites are those residents of every household that no one is aware of. The reason for this is that dust mites are very, very tiny. In fact, they are microscopic. Although they themselves are harmless, their waste and bodies can pose a problem.
Mold is usually found in dark, musty, and damp places. However, the spores that it produces can mix and spread through the air. These spores, when inhaled, can trigger allergies.
Pet dander is basically the small flakes of skin that your pet sheds. These are although very small, but they can trigger allergies when inhaled.
What Makes an Air Purifier Great for Allergies?
Low Noise Levels
Some asthma attacks are triggered by loud sounds, so finding an air purifier like Airthereal PH260 with ultra-low sounds when on sleep mode is recommended.
Number and Nature of Filters
Multiple filtration stages mean a bigger improvement in indoor air quality and removal of more airborne allergens. Air purifiers with up to seven filtration stages, including true HEPA filtration and activated carbon, are best for reducing asthma symptoms and allergic rhinitis.
Air purifiers come with different types of filters. Depending on the size of particles you are concerned about, you will need a different filter to catch them. Pollen and pet hair are much larger than the airborne particles that cause bad odor.
For allergies, it would be wise to pick an air purifier that will trap small, medium, and large particles. A high-efficiency particulate air (HEPA) filter for permanent and portable air purifiers is recommended.
The best air purifiers for allergies and asthma can remove airborne particles and gaseous pollutants as tiny as 0.1 microns.
High Fan Speeds
For faster disinfection, a higher fan speed is important. The higher the fan speed, the faster the purification process.
What Do I Need to Know Before Buying an Air Purifier for Allergies?
There are quite a variety of air purifiers with different features and picking the right one might be a little confusing if you don't know exactly what to look for.
Here is a checklist of what to keep in mind when shopping for an air purifier for allergies.
The Type of Filter
Depending on what you want to filter from the air, different air filtration processes work best under different requirements. There are also varying sizes of air pollutant particle sizes that should also be considered.
For example, pollen and pet hair are large-size particles, dust is medium-size, and smoke is small-size. All these will require a unique filtration process. HEPA is the recommended air filtration for allergies due to its diversity and effectiveness in air disinfection.
Air Purifier Noise Level
Most likely, you'll be using your air purifier at night and you want a silent appliance that will give you and the young ones a peaceful night's sleep.
Check on the noise levels, measured in decibels (dB) on the product's specification to ensure it's as low as possible. While most air purifiers make less noise when on the low operation mode, there are still air purifiers operating at high speed with very low noise levels.
Some allergies and asthma are triggered by loud sounds so this is something you want to keep in mind when shopping for an air purifier.
Air purifiers will always run for long hours sometimes for a whole day when you spend most of the time indoors. Although they consume less energy, when left to run throughout they can negatively impact your electricity bill. Consider investing in an air purifier with a timer and smart control. The air purifier will automatically monitor air quality and shut off once the disinfection is complete.
Best Types of Air Purifiers for Allergies
There are several types of air purifiers but not all are effective in removing airborne allergens.
Here are some best types of air purifiers for allergies.
HEPA purifiers come with a very advanced air filter that can filter particles as small as 0.2 microns. This type of filtration purifies air up to 99.97% contaminant free levels.
HEPA purifiers will filter dander, dust, mold, and also pollen particles from the air.
They are, however, unable to trap microorganisms like bacteria, germs, and viruses that are smaller than 0.2 microns.
HEPA is very effective not only in removing allergies but generally disinfecting air, which makes it so popular and many people's favorite air purifiers.
Ionic Air Purifiers
Ionic air purifiers are very quiet and operate without a motor. These air purifiers will clean almost everything in the air apart from removing odors.
They will remove dander, dust, allergens, smoke, fumes, bacteria, and viruses by emitting negative ions into the air that combine with air pollutants, making them heavy to stay in the air and instead fall to the ground.
Ionic air purifiers need regular cleaning for optimum performance.
Central Air Cleaners
Central air cleaners require professional installation to connect to central cooling and heating systems. They have up to 98% efficiency and will reduce asthma, allergies, and viruses by a bigger margin within your home. The high-end models remove particles as small as one micron and also clear all the dander and smoke particles.
