Replacement filters for AprilAire Allergy+ Pet True HEPA air purifiers are a great choice for those with asthma. Filtrete Ultra Allergen Healthy Living 1500 air filters and Honeywell HRF-ARVP300 HEPA prefilter combo packs are also excellent options. Ionizers are better at eliminating larger particles found in smoke, but they may not be as effective at removing pollen or dust. These purifiers can also generate a small amount of ozone, which can be irritating for people with asthma or COPD.
Ozone is a gas that is created when oxygen molecules are split into single atoms and then recombine with other oxygen molecules. It is important to note that ionizers and other air filters that produce ozone should be avoided if you suffer from asthma. The American Academy of Allergy, Asthma & Immunology (AAFA) recommends air purifiers with certified filters suitable for people with asthma and allergies, which can remove almost 98% of allergenic particles from the air. True HEPA filters are effective at eliminating these contaminants from the air, but they have some drawbacks. For instance, a Clean Air Delivery Rate (CADR) of 250 for smoke means that the air purifier can clean the air in a 250-square-foot room of smoke in one hour. However, an open air stream or door can cause unfiltered air to enter a room faster than the purifier can absorb it. One way to combat this issue is to use a professional-strength adhesive tape to seal the entire perimeter of the filter.
This will help ensure that no unfiltered air enters the room. A well-designed purifier can capture virtually all airborne allergens, such as pollen and mold spores, as well as bacteria, viruses, and smoke. A randomized group of participants used air purifiers in their bedrooms while a control group did not. The results showed that those who used an air purifier had significantly lower levels of airborne allergens in their bedrooms than those who did not use one. Air purifiers filter particulates from the air, such as dust or smoke, and return clean air to the room. They can also help remove harmful particles from the air caused by smoke, which can occur during times of wildfires.
The Levoit Core Mini air purifier was able to effectively clean the air during testing, although it performed better when it was at a high temperature. When selecting an air purifier for your home, it is essential to consider factors such as CADR ratings, filter types, and energy consumption. It is also important to make sure that your filter is properly sealed so that no unfiltered air enters your home.
