Product Details
These replacement filter kits are built to fit Carrier 40MHHAQ30/36 and 45MHHAQ30/36 wall-mounted ductless indoor units. Clean filters ensure your system runs efficiently and your indoor air stays fresh—whether you're cooling a bedroom, office, or mixed-use space.
This kit is guaranteed to fit the following Carrier indoor unit models:
- 40MHHAQ30XA301
- 40MHHAQ36XA301
- 45MHHAQ30XC301
- 45MHHAQ36XC301
Large Washable Screen Filter Dimensions: 18-1/4" x 16-1/2"
Maintenance & Care
Clean the screen filters every two weeks with a vacuum using a soft-bristle brush attachment. In more demanding environments—like homes with pets, indoor smokers, or garages—filters can also be gently washed with warm, soapy water. Let the filters dry completely out of direct sunlight before reinstalling.
⚠️ Important: Never operate your unit without the filters installed. Consider keeping a second set to stay on schedule with cleanings.
Replacement Guidance
Although washable and reusable, screen filters lose efficiency over time. For optimal airflow and indoor air quality, replace them every 12 to 24 months, depending on usage and care.
Optional Activated Carbon Freshness Filter
This kit includes an optional freshness filter that fits into the pre-molded holder inside your screen filter. It contains activated carbon media to help absorb odors and reduce VOCs from tobacco, pets, and cooking, providing a noticeable upgrade to your system’s air quality performance.
Filter Dimensions: 8.4" x 2"
Maintenance & Care: Do not wash. Vacuum every two weeks using a soft-bristle brush. Replace every 6 months to maintain odor absorption and filtration performance.

Carrier FAQs
Fit guaranteed for the models listed
This listing is sold by indoor unit model. Under our Compatibility Guarantee, it fits every model listed on this page. Check the model number on your indoor unit's nameplate, typically on the right-hand side of the unit or on the bottom edge facing the floor, before ordering. Go by the nameplate rather than the owner's manual, since one manual usually covers several models.
If your model isn't listed, keep the filters sealed until you've confirmed the fit. Opened filters can't be returned. Send us your model number and we'll confirm the right part before you order.
About product images: Photos are illustrative. Multi-pack images are created digitally from a single filter, and color, shading, backgrounds and the look of the filter media may differ from the product you receive. Images do not indicate added layers, backings or a higher filtration level than stated. Filtration rating, materials, dimensions and pack quantity are defined by the product description and specifications.
Returns & Exchanges
We want every order to go smoothly, and if something is not right we want to make it right. At the same time, for the health and safety of everyone — our team, other customers, and the facilities these products are used in — we cannot resell opened or used filtration and air quality products. Our policy below is built around that reality. If you have any questions about a product before ordering, please reach out — we would rather help you get the right thing the first time than deal with a return after the fact.

Opened or used items are not eligible for return or refund under any circumstances. Products designated as Special Order, Clearance, Discontinued, or Final Sale along with Equipment are not eligible for return or exchange. All other returns require items to be unused, in new condition, and in original packaging with all accessories and documentation included.

Returns sent without an RMA may be refused.
Refunds are processed within 10 business days of receiving and inspecting the returned item. You will be notified by email when your refund has been issued.

Order Cancellations
Contact us immediately if you need to cancel an order. Not all orders can be cancelled once placed — freight and special-order items in particular may ship before a cancellation can be processed.
