Are Water Purifiers Efficient?

Yes. Air purifiers are efficient. However, air purifiers do not remove or neutralize all aggravating particles in your home. It happens because there are many particles that sit on soft surfaces like carpeting, furniture, and bedding and hard surfaces like walls too.

The majority of the time, air purifiers may remove the following particles.


These types of particles can create an adverse immune response. The response can be in the form of allergies or asthma. The most common airborne allergens are pollen, pet dander, and dust mites. The purifiers work efficiently with the help of high-efficiency particulate air (HEPA) filter to trap airborne allergens.


For people with asthma and other lung-related problems, molds, which are indoor particles, become more dangerous. To some degree, air purifiers may work. However, filtration is even more effective to remove mold from the air. If you have an air purifier with a HEPA filter, you do not need to worry as it reduces humidity levels in your home.


As the air purifiers include filters, they may also remove smoke in the air, including smoke from landscape fires and tobacco smoke.
