Not sure which type of air filter is right for your central air needs? We've got some recommendations.

I have a Dog and/or Cat

The primary concern for dog and cat owners that can affect indoor air quality is pet hair and dander, which can easily become airborne without the proper filter.

For cat and/or dog owners, we recommend an air filter with a MERV 11 rating or higher. these filters are best for capturing pet dander and keeping it out of your home's air supply.

I have Asthma or other Respiratory illnesses

If you or anybody in your household suffers from asthma and other respiratory illnesses, then choosing the right filter is just as important as making sure to change your filter as often.

For those with asthma, we recommend an air filter with a MERV 13 rating or higher, as these are among the best air filters on the market. Specifically, these can capture everything from lint and household dust to pollen, smoke, smog, bacteria, and mold spores.

I am a Smoker

If there are any smokers in your household, having the correct air filter can help to minimize the amount of second-hand smoke that circulates in the air in addition to helping your home smell fresher.

For a smoking household, an air filter with a MERV rating ranging from 11 to 13 is best. These are rated to filter out smoke and smog most effectively.

I have Allergies

If are allergic to common allergens such as dust mites, mold or pollen, the good news is that most AC filters on the market with a MERV 8 rating or higher will be effective in filtering out most of these allergens.

However, if you have allergic to cats or dogs and have either of these animals in your home, keep in mind that a MERV 11 filter or higher is best at filtering out any pet dander. Ultimately, the best choice in filter really depends on what your specific allergens are.

In conclusion

No matter which type of air filter you purchase, keep in mind that changing filters frequently is the best way to ensure optimal air quality in your home. The frequency will vary depending on the type you buy, but most should be changed every 45-90 days.
