F100F1625: verified filters for this cabinet

Only manufacturer-documented cabinet-to-filter relationships are shown.

Not sure where to look? See exactly what to copy

Use the label you can reach safely. Start with the filter already in place, if you can reach it through a normal filter slot or return grille. You may also find a separate filter cabinet near the equipment. Copy exactly what is printed; FilterFound will say when another detail is needed.

Best starting point

Current filter

Read the frame of the filter already installed. Keep every letter, number, dash, and suffix.

Copy: full part or model number

Strong alternative

Filter cabinet or media air cleaner

Look on the outside of the housing around the filter slot or door. This label is often different from the furnace label.

Copy: cabinet or air-cleaner model

If that is all you can find

Furnace or air handler

Use the model from the equipment exterior. It can start the lookup, but it may not identify one installed filter by itself.

Copy: equipment model, not the serial number

Fallback

Filter size

Read the nominal size printed on the filter edge. Several different filters can share the same nominal size.

Copy: the full size, for example 20 × 25 × 5

How do I change the filter once I find the correct replacement?
  1. Read the filter and equipment instructions. Turn the system off before opening its normal user-access filter slot or return grille.
  2. Before removing the old filter, note or photograph the full part number, size, and airflow arrow. Check the cabinet label too, if present.
  3. Use the replacement verified for your installed filter and cabinet. Follow the manufacturer's instructions for its frame, rails, and airflow direction; do not force it into place.
  4. Close the filter cover and restart the system only when the filter is securely installed. If the filter is not safely accessible or the instructions are unclear, consult a qualified HVAC professional.

Generic steps do not replace model-specific instructions. A matching nominal size or MERV rating alone does not prove compatibility.

Do not remove electrical or service panels to find a label. Use only the filter or exterior labels you can reach safely.

Type exactly what you see. A size alone may need another check.

Verified filters for this cabinet

Match the filter you already have first

Every option below is verified for F100F1625. If you are replacing an installed filter, start with the exact part number printed on that filter.

Do not choose by MERV alone.Format means how the replacement is physically supplied (for example, a complete box filter versus replacement media), not how strongly it filters. This cabinet has verified options in more than one format. Match both the part number and the format you already use before buying.
No filter is installed to match

FilterFound has verified that every option above fits F100F1625, but the cabinet model alone does not tell us which verified option your installation is set up to use.

Do not choose by MERV alone. If no current part is available to copy, use the manufacturer documentation for this exact cabinet model to identify the filter format or part number. If you still cannot verify it, stop before buying rather than guessing.

I don't know which filter is installed
