We love being able to provide a service that helps keep our community healthy. Our air filters come in a variety of sizes, including 20x20x1, 16x25x1, 20x25x1, and 20x25x5, and are available in different MERV ratings to cater to various needs.

A MERV (Minimum Efficiency Reporting Value) rating is a scale that measures the ability of filters to trap particles, ranging from 1 to 20 (with 20 capturing the smallest particles). Our filters come in MERV 8, MERV 11, and MERV 13 ratings, catering to different levels of protection and needs, such as standard, superior, and optimal filtration, as well as odor elimination.

We understand the importance of finding the right filter size for your system. The nominal size is a rounded number, while the actual size is the precise measurement. We recommend measuring your current filter and then rounding up to the nearest inch to find the corresponding nominal size.

Changing your air filter regularly is crucial for maintaining a healthy lifestyle, as breathing dirty air can lead to various respiratory issues. We generally recommend replacing your filter every 90 days, but this may vary based on factors such as filter size, pet ownership, and allergy concerns.

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 will depend on the specific needs of your home or business.

At Filterbuy, we are committed to providing clean indoor air for all. We manufacture our products in the USA, using high-quality materials, and offer a subscription service to make the filter replacement process easier. Our green frames symbolize the peace of mind that comes with knowing your home or business is being properly cared for.
