Air Filters FAQs

Here are answers to some of the most common questions we get asked about air filters..

Air filters for home help improve indoor air quality by removing harmful particles such as dust, pollen, pet dander, and other allergens. They can also help reduce odors and prevent the growth of bacteria and viruses, creating a healthier living environment for you and your family.

It is recommended to replace air filters for home every 3 months or sooner if you have pets or allergies. However, this may vary depending on the type of filter you use and the level of pollution in your area.

There are several types of air filters for home, including, MVHR air filters, HEPA filters, activated carbon filters, UV-C filters, and electrostatic filters. Each type has different benefits and is designed to target specific types of air pollutants.

Air filters for home can help reduce the spread of COVID-19 by capturing and filtering out respiratory droplets that may contain the virus. However, it's important to note that air filters alone are not a substitute for other preventative measures such as social distancing and mask-wearing.

Air filters for home can be purchased at most home improvement stores, online retailers (such as ourselves!|), and from HVAC contractors. It's important to choose the right size and type of filter for your specific HVAC system to ensure proper filtration and airflow.

For allergy sufferers, HEPA filters (High-Efficiency Particulate Air) are often considered the most effective option. These filters can capture up to 99.97% of particles as small as 0.3 microns, including allergens like dust, pollen, pet dander, and mold spores. Choosing a HEPA filter with a higher MERV rating can provide even better filtration for allergy relief.
