For an AC filter with a metal frame, choose a reusable filter sized to your system: UBeesize is a MERV 8 option with an aluminum frame, while WATTRIP offers a reinforced metal frame in a two-pack. CoreCarbon’s hinged frame is designed for a specific fan-coil replacement size. Handua is a steel return-air grille that holds a separate one-inch filter, and Trophy Air is another aluminum-framed reusable option.
| Product | Best For | Frame Or Holder |
|---|---|---|
| UBeesize 20x25x1 | Washable MERV 8 filtration | Aluminum frame |
| CoreCarbon 16 3/8 x 21 1/2 x 1 | Matching fan-coil filter size | Hinged filter cage |
| Trophy Air 20x25x1 | Layered reusable construction | Aluminum layers |
| WATTRIP 20x23x1 2-Pack | Reinforced mesh and two filters | Aluminum frame and painted steel mesh |
| Handua 20×20 Return Grille | Wall or ceiling filter access | Steel grille; filter sold separately |
UBeesize 20x25x1 Washable Filter
This reusable electrostatic HVAC filter has an aluminum frame and a stated MERV 8 rating. The listed actual dimensions are 19.75 x 24.65 x 0.82 inches, so compare those measurements with the system’s filter slot rather than relying only on the nominal 20x25x1 label.
Its pleated layers are described as capturing dust, pollen, and pet hair. To maintain it, the manufacturer recommends washing with water and a little detergent, letting it dry naturally, and cleaning it every three months.
- Best for: Buyers looking for a washable, framed MERV 8 filter in a common nominal size.
- Why it was selected: It explicitly combines an aluminum frame, reusable construction, and a stated filtration rating.
- Consider: Confirm the actual dimensions and system requirements before ordering; the filter must dry before reinstallation.
CoreCarbon Hinged Filter Frame
CoreCarbon’s filter is listed at 16 3/8 x 21 1/2 x 1 inches and is described as compatible with replacement references KFAFK0212MED and 317659-402. Its robust hinged cage holds washable polyester fiber media. The media can be rinsed with low-pressure water, dried, and reinstalled; the product description also says new media can be installed.
- Best for: Buyers replacing an existing filter with the same listed dimensions or matching one of the specified fan-coil references.
- Why it was selected: It includes a reusable hinged frame rather than just loose filter material.
- Consider: Its specific size makes measurement essential. Do not assume it fits a different nominal filter opening.
Trophy Air 20x25x1 Reusable Filter
This 20x25x1 reusable AC and furnace filter uses four layers of aluminum and two layers of electrostatic media, according to the product details. Trophy Air describes the design as intended to support airflow and capture airborne particles. The provided information does not state a MERV rating.
- Best for: Buyers who want a reusable filter with multiple aluminum and electrostatic layers.
- Why it was selected: Its listed construction makes it directly relevant to searches for a metal-framed AC filter.
- Consider: If you need a specific filtration rating, verify that requirement separately; no MERV rating is provided in the supplied product details.
WATTRIP 20x23x1 Two-Pack
WATTRIP’s two-pack includes reusable 20x23x1 electrostatic HVAC filters with a stated MERV 8 rating. Each filter has a reinforced aluminum frame and painted steel mesh. The seven-layer design is described as four metal-mesh layers, two nylon-media layers, and one filter-cotton layer, intended to capture dust, lint, and pet hair.
- Best for: Buyers seeking a two-pack with a reinforced frame and layered mesh construction.
- Why it was selected: It combines an aluminum frame with steel mesh and a stated MERV 8 rating.
- Consider: The 20×23 nominal size differs from common 20×25 filters, so check the system’s required dimensions.
Handua 20×20 Steel Return Grille
This product is a steel return-air filter grille, not a complete filter. It fits a stated 20×20-inch wall opening and has listed outside dimensions of 22 5/8 x 22 5/8 inches. The removable door provides access to a separate one-inch-thick filter, which is not included. Its 40-degree angled fins are described as supporting airflow.
- Best for: Buyers who need a steel wall or ceiling return grille that holds a one-inch filter.
- Why it was selected: It adds a metal filter-holding option for installations where the grille and filter are separate components.
- Consider: Measure the wall opening; the listed size refers to the opening, not the grille’s outside dimensions. Buy a filter separately.
Buying Guide: Choosing An AC Filter Metal Frame
How do you choose the right size?
Measure the existing filter or the filter slot, and compare width, height, and thickness with the product’s actual dimensions. Nominal labels such as 20x25x1 may not equal the physical measurements. For a return grille, measure the wall opening separately: the Handua listing distinguishes its 20×20 opening size from its larger outside dimensions.
Do you need a filter or a frame?
A reusable filter such as UBeesize, Trophy Air, or WATTRIP is a complete filter assembly. CoreCarbon includes a hinged cage and washable media. Handua is a grille that holds a separate filter, so it is the relevant choice when the existing grille needs replacement rather than the filter alone.
What should you compare in washable filters?
Check the stated MERV rating when available, the frame material, filter dimensions, and cleaning instructions. UBeesize and WATTRIP list MERV 8; the supplied Trophy Air and CoreCarbon details do not state a MERV rating. Reusable products require cleaning and full drying before they go back into the system.
Does a metal frame guarantee compatibility?
No. Frame material does not establish fit or suitability for a particular HVAC system. Confirm the required size and any filtration specifications in the system documentation. For a replacement part, compare the existing product’s measurements or reference number with the listing.

No. It is a steel return-air grille designed to hold a separate one-inch filter, which is not included.
