RayAir Supply 20×25 Replacement Filter Pads (3 Pack)
RayAir Supply’s 20×25 replacement filter pads come as a 3-pack designed for Dynamic Air Cleaner frames. The pads use three changes of fiberglass media with an activated carbon center, aiming to capture odors and certain VOCs alongside particulates. The product is manufactured in the USA and is tested under recognized ventilation and filtration standards, including ASHRAE 52.2 and ANSI/AHAM AC-2006. The replacement pads align with standard 20×25 frame dimensions and offer a CADR-conscious replacement option for mid-to-large furnaces.
Features include a USA-made material base, UL-classified components, and a focus on a multi-layer filtration approach to improve indoor air quality with routine changes. Each order provides three pads that fit the Dynamic Air Cleaner frame size 20x25x1, with the actual replacement pad size specified as needed by the model. This selection suits homeowners looking to restore or maintain airflow efficiency without changing the entire purifier assembly.
RayAir Supply 16×25 Replacement Filter Pads (3 Pack)
This 16×25 kit mirrors the same three-pack structure with fiberglass media and an activated carbon center. It is designed for Dynamic Air Cleaner frame sizes of 16x25x1 and is manufactured in the USA. Like the 20×25 variant, it undergoes testing aligned to industry standards for ventilation devices, ensuring reliable CADR performance after each replacement. This option is suitable for homes using 16×25-dimension purifiers, providing consistent filtration as part of routine maintenance.
The pads’ added carbon layer targets odor and some VOC removal, complementing particulate filtration. Expect three changes per order, making it a straightforward maintenance replacement for compatible furnaces.

This listing reiterates 20×25 replacement pads for the Dynamic Air Cleaner, including an actual pad size of 18.5″ x 22.5″. The three-packs emphasize a triple-change approach, with fiberglass media and activated carbon centered between layers. The product notes highlight USA manufacturing and CADR testing, aligning with consumer needs for dependable furnace filtration performance over time.
Users should check their furnace model compatibility to ensure the exact frame size matches the 20×25 specification. Regular changes help maintain airflow and filtration efficiency in spaces with higher pollutant loads or odor control requirements.

As with similar products, consider the replacement cadence—every 1 to 4 months depending on local air quality—and the overall filtration goals, including odor suppression via the carbon center when present in a given model.
Buying Guide: Key Purchase Considerations For Furnace Electronic Air Cleaners
- Frame compatibility: Confirm exact frame size (for example, 20×25 or 16×25) and thickness to ensure a proper seal and filtration efficiency in your furnace’s electronic air cleaner.
- Filtration media: Look for a combination of fiberglass media with activated carbon center if odor control is a goal. Carbon layers help tackle VOCs in addition to particulates.
- Material sourcing: USA-made components can offer quality assurances and traceability. Check for UL classifications and conformity to recognized standards (ASHRAE, ANSI/AHAM).
- Replacement cadence: Most installations call for a 1- to 4-month replacement interval depending on usage, occupancy, and indoor air quality. Some manufacturers specify exact change counts per order.
- Actual pad size vs. nominal size: Some listings provide the actual pad dimensions (e.g., 14.5″ x 22.5″ or 18.5″ x 22.5″). Verify these to ensure proper fitment in your purifier frame.
- Installation and accessibility: Replacement pads should be easy to insert and remove without disassembling major components. Access to the filter cavity is an important factor in routine maintenance.
- Cost per change vs. pack size: Multi-pack options (3-pack or 7-pack) offer cost efficiency and reduce the frequency of ordering. Evaluate total cost of ownership over a season.
- Standards and testing: Products tested for CADR and compliance with ventilation standards provide a reliability baseline. Look for product specs referencing ASHRAE 52.2 and AC-2006 where applicable.
- Future-proofing: If your system may upgrade to a model with different frame sizes, consider whether the brand offers multiple compatible sizes or easy-to-find replacement pads across sizes.
Additional Considerations for Electronic Air Cleaners in Homes
Beyond filter pads, regular maintenance of the entire furnace air cleaning system contributes to indoor air quality. Consider pairing replacement pads with routine duct cleaning, ensuring seals around the purifier housing remain intact, and monitoring ambient air quality indicators in busy living spaces. For electronics-friendly environments, products like specialized electronic cleaners (when used appropriately per manufacturer guidelines) can support long-term reliability of control boards and switches without leaving residues. Always follow safety precautions and disconnect power when performing maintenance.
