We love being able to provide a service that helps keep our community healthy. Our range of air filters, including MERV 8, MERV 11, MERV 13, and Odor Eliminator, cater to different needs, from standard filtration to optimal protection and odor elimination.

The MERV (Minimum Efficiency Reporting Value) rating determines the filter's ability to trap particles on a scale of 1-20, with 20 being the smallest microns captured. MERV 8 filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate, MERV 11 filters are ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers, and MERV 13 filters are perfect for larger homes or businesses and those who want the best possible filtration experience.

Our Odor Eliminator MERV 8 air filters with activated carbon are perfect for homes or businesses that want to inhibit unpleasant smells with reliable MERV 8 quality.

When it comes to choosing the correct filter size, it's important to understand the difference between nominal size and actual size. The nominal size is a rounded number, while the actual size is the precise measurement of the filter.

Replacing your air filter regularly is crucial to maintain a healthy lifestyle, as breathing dirty air can put you at risk of developing asthma, allergies, and other respiratory ailments. We generally recommend replacing your filter every 90 days, but this may vary based on factors such as filter size, pet ownership, and the presence of allergy sufferers or children in the home.

Our air 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. The number of filters you need depends on the number of vents in your home.

Changing your air filter is a straightforward process. After finding the right size, turn off the power supply, remove the cover from your intake vent, take out the old filter, and insert the new one in the direction of air flow. Then, replace the cover and turn the power back on.

At Filterbuy, we are committed to championing indoor air quality and ensuring that everyone, everywhere, has access to clean indoor air. Our wide range of custom sizes, expert services, and American-made products are designed to provide you with the perfect fit and the peace of mind that comes with breathing crisp, pure, fresh air.
