Maintenance & Care Instructions
- Cleaning Frequency: Vacuum the filter gently with a soft-bristle brush every two weeks. When visibly dirty, wash with a mild detergent in lukewarm water to remove dust and buildup.
- Drying: Allow the filter to dry completely in the shade before reinstalling. Avoid direct sunlight or high heat. Do not operate your mini split system while the filter is removed or drying, as this can allow dust to enter the unit and cause internal buildup or mold growth.
- Replacement: With regular cleaning, the filter can be reused for an extended period. For best performance, replace it annually—or sooner if it shows signs of wear, damage, or cannot be fully cleaned after washing.
One pack contains two (2) filters.
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.
Eligibility
Opened or used items are not eligible for return or refund under any circumstances. Products designated as Special Order, Clearance, Discontinued, or Final Sale are also 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.
30-Day Return Policy
Unopened, unused items may be returned within 30 days of delivery, subject to a restocking fee of at least 25% of the purchase price. Original shipping costs are not refunded. Return shipping is the buyer's responsibility.

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.
Exchanges — Standard Restocking Charge Waived
Exchanges for unopened, unused items are not subject to a restocking fee. Contact us at Help@HEPAFilterSales.com before returning any item to arrange an exchange and receive expert advice on the correct solution.
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.
