Having the correct size air filter matters just as much as having a dust- and contaminant-free filter. When you install an air filter that is too large or too small, air will flow around the filter instead of through it and enter your space with all the contaminants that would have otherwise been filtered out. So, make sure you consider the exact or custom size you need when shopping for new air filters. Luckily, you can find every size imaginable at Remember The Filter. This includes 10x24x1 air filters in various styles, including spun glass and pleated configurations. Browse our selection of 10x24x1 air filters to find the best options for your HVAC system.
