Why should I change my air filter?

To maintain a healthy lifestyle, as breathing dirty air can put you at risk to develop asthma, allergies, and other respiratory ailments. Plus, old filters can cause system defects which may lead to unwanted expenses via energy costs and repairs.

When should I change my air filter?

We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. But this is subject to change based on filter size and variable factors for pet owners, allergy sufferers, homes with children, etc.

Will these air filters fit my system?

Most of our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system as long as you choose the proper size. But if you see a specific brand name on a listing, make sure it matches your unit model.

How many air filters do I need?

This varies for every customer depending on specific needs such as the number of vents in your home. However, our selection includes package quantities that range from 1 to 12 filters, so no matter what your situation may be, we've got you covered.

How do I change my air filter?

After finding the right size, turn off the power supply and remove the cover from your intake vent before taking out the old filter. Then just insert your new filter to match the direction of air flow, replace the cover, and turn the power back on.

Great filters for my 5 ton unit- well made and designed for airflow and hold up! Very well! MUCH BETTER than Lowes or HD FILTERS Whistling stopped when I changed to the filters!!

I have allergies, so I was looking for a filter that would help create cleaner air in my room. Installation was quick and hassle-free, and the price felt like a great value. The filter fit perfectly in my vent, and I’ve already noticed an improvement—there’s better airflow and noticeably less dust.
