Air Filters Delivered is now Aerostar Air Filters. Shop home and business air filters by size, depth, and MERV rating, order a custom filter when a standard size will not fit, or set up delivery on the schedule that works for you.
Our name may have changed, but the quality of our replacement air filters and customer service has not. Neither has the site's ease of use - start with the dimensions and depth shown on your current filter, then select the MERV rating that fits your equipment. If your system takes an uncommon size, we can build filters to the exact measurements you provide. Customers who prefer regular delivery can still choose a schedule through Subscribe & Save, so new filters arrive before they are due for replacement.
A New Name for Your Replacement Filter Source
AirFiltersDelivered.com has become AerostarAirFilters.com. Other than our new brand name, it's business as usual. When it is time to replace a furnace or HVAC air filter, you can find the right fit for your home or business here without missing a beat.
Filter replacement should be simple, and that hasn't changer either. Read the size on the frame, confirm the depth, choose the filtration level that suits your system, and order the replacement you need.
Shop for Your HVAC System
Start with the filter already installed. The frame usually lists its length, width, depth, and MERV rating. Take a photo before you remove it if the print is faded or you replace filters in more than one location. A clear photo saves time the next time you need to order.
Correct filter dimensions prevent fit problems. A filter that is too small can leave gaps around the frame. A filter that is too large may bend or refuse to slide into the slot. Read our guide to actual versus nominal filter size if the measurements on the frame do not match what you expected. It explains the difference between the size printed on a filter and its physical dimensions.
Once you have the size, choose the MERV rating that fits your equipment and household needs. The EPA recommends using the highest-rated filter your system fan and filter slot can accommodate. Check your system manual or talk with an HVAC technician if you are unsure. Or, for a closer look at the rating systems you may see on filter packaging, read our MERV, MPR, and FPR ratings guide.
Custom Sizes for Hard-to-Fit Systems
Some air filtration and furnace systems take filter sizes that are hard to find in a retail aisle. That does not mean you need to settle for a loose fit or struggle to make a standard filter work. Use our custom filter builder to enter the actual length, width, depth, and MERV rating your system needs.
Measure the filter itself rather than the vent opening. Check all three dimensions. If you are replacing a filter in a return vent, furnace cabinet, or air handler, make sure the replacement has enough room to slide in without bending the frame. A proper fit keeps air moving through the filter instead of around it.
Keep Air Filter Replacement on Schedule
Replacing filters is a task less likely to be overlooked when new filters arrive before the old one is overdue. With Subscribe & Save, you can choose a delivery schedule that fits your household or business. Customers can pause, skip, or cancel a current subscription as needs change, and eligible recurring shipments receive up to 8% off with free delivery.
Choose a schedule that reflects how your system runs. A home with pets, frequent heating and cooling use, or more dust in the air may need replacements sooner than a low-use property. Check the filter regularly. If it is visibly loaded with dust, replace it. The condition of the filter matters more than the calendar alone.
Need Help Choosing a Filter?
If you need help finding a size, choosing a MERV rating, locating a custom option, or managing a current subscription, our Customer Support team is ready to help. Have the size from the filter frame handy. If you have a question about a product, a photo of the label can help us point you in the right direction.
Choosing the right filter does not need to turn into a lengthy project. Start with your system’s dimensions, make sure the replacement fits, and order the filtration level that makes sense for your home or business.
