Frequently Asked Questions (FAQ)

What is the best air purifier for asthma and allergies?

You can easily find several air purifiers using Amazon’s search tools and filters, which have positive reviews and the lowest price. Be sure to choose an air purifier that filters both large and small particles and that the filter changes easily. The most important factors to consider when selecting an air purifier for these purposes are: HEPA filter, carbon filter, IAQ, noise level, and price.

Do air purifiers help allergies and asthma?

Air purifiers do help allergies and asthma symptoms, but only in addition to correct marketing. They can help to remove allergens, dust, and small particles from the air in your home, which will make it easier to breathe for people who suffer from allergies or asthma.

If you have pets in the house, an air purifier will do wonders for the air quality. There are other steps to take as well in order to ensure your safety and the safety of those who suffer from allergies or asthma. These include dusting regularly, vacuuming, and mopping.

Are air purifiers good for asthma sufferers?

Air purifiers are just one of many measures that can be taken to control the environment in your home to reduce asthma triggers. The best thing about air purifiers is that they are easy to use. Simply plug them in and let them do the work for you. Depending on the type of machine, they either have built-in HEPA filters or use UV lights.

UV light is one of the best uses of the technology because it doesn’t actually change the air, but instead, purifies it. While HEPA filters cannot eliminate all of the allergens in the air, they are more cost-effective.

What air purifiers do allergists recommend?

The primary air purifiers recommended by allergists are HEPA (high-efficiency particulate air) purifiers. These are air purifiers which capture and eliminate particles such as dust, mold, pet dander, pollen, bacteria etc. that hang around in your living space. That by itself is pretty good, however, there are some additional features that make these stand out.

True HEPA air purifiers remove 99.97% of particles as small as .3 M and are able to capture particles as small as .1 M. Some of these have what’s called a “multi-stage filtration” system which basically uses two or three levels of filtration, each with a different size or power, to ensure that even the smallest particles are removed. Some also have modes to provide automatic timed cleaning of surfaces.

Conclusion

People who suffer from seasonal allergies have to live with a variety of symptoms throughout the year. Remedies such as steroids, antacids, antihistamines, and nasal sprays can all help with various symptoms, but the best way to manage your symptoms is to find a permanent solution.

No one in their right mind wants to spend their time cleaning and dusting the interior of their home year-round, so finding a way to cut down on dust would make that chore irrelevant. This is where home air purifiers come in. These devices are specifically designed to trap allergens and allergens in the air so you’ll be breathing clean air.
