Are you wondering if you can use a generic brand of 20x25x1 air filters in your furnace or AC unit? The answer is a resounding yes, as long as your home has an air filter with a color-changing technology of MERV 8. This filter should be slightly smaller on each side of the groove in the filter housing, allowing you to slide it in and out with ease. If you notice smoke-filled air finding its way around the clogged filter instead of going through it, it's time to install a new one. The air is charged with particles and the results are measured after passing through the filter only once. Filters don't need to have a “hermetic” seal, but they should be easy to install and uninstall without any problems.
Filters with higher MERV indices trap small particles more effectively than filters with lower MERV indices. Filterbuy offers a wide range of sizes, thicknesses, and MERV ratings so you can find reliable aftermarket air filters for residential use, as well as for commercial or industrial applications. If you're looking for qualified filters, we recommend the Nordic Pure MERV 12, a filter in perfect condition that usually costs less, as well as two other filters that are also fine. Remember that the more filter has to pass through the air, the harder it will be for the unit to work properly. The air filters can be changed from behind the intake grilles (often referred to as air filters or air conditioning filters) or in the boiler case of the central air unit (often referred to as “heating filters”).
We have filters and pads for humidifiers from all major manufacturers (including Air King, American Standard, Aprilaire, GeneralAire, and Honeywell).3M prefers the MPR, or microparticle performance rating, for its filters, while Home Depot uses the FPR, or filter performance rating, for filters that bear the Home Depot name.
MERV
stands for Minimum Efficiency Reporting Value and is a classification that measures the filtration capacity of an air filter. When it comes to choosing an air filter for your furnace or AC unit, it's important to consider both size and MERV rating. The size should be slightly smaller than the groove in your filter housing so that it can slide in and out easily. The MERV rating should be high enough to trap small particles effectively.Filterbuy offers a wide range of sizes and MERV ratings so you can find reliable aftermarket air filters for residential use, as well as for commercial or industrial applications. We recommend Nordic Pure's MERV 12, a filter in perfect condition that usually costs less than other brands. Additionally, remember that the more filter has to pass through the air, the harder it will be for your unit to work properly. So make sure to change your air filter regularly.
