Honeywell Dehumidifier Filters: DR90, DR120, DH65 Fits Compared

Best for
Trying a MERV 13 DR90 filter first

Best for
DR90 or DR120 owners stocking up

The 14 x 17.5 x1.75 MERV 13 four-pack is a third-party Honeywell DR90 filter and Honeywell DR120 filter replacement, listed as a match for part 50070171-002. It is not made by Honeywell; it is sold by an outside brand as compatible. The listing rates it MERV 13 and claims it removes at least 95% of airborne particles, including dust, smoke, pollen, fibers and pet dander.

The package holds four filters, and the seller recommends replacing them every six months, so one box covers roughly two years of use for a single dehumidifier. That makes it the practical pick if your DR90 or DR120 runs constantly in a basement, garage or game room. The listing’s claims about “premium materials” are marketing language without specifics, and it gives way to the two-pack if you just want to confirm the fit before buying in bulk.

• Size 14 x 17.5 x 1.75 inches
• Listed for Honeywell DR90 and DR120 (50070171-002)
• MERV 13 rating
• Four filters, six-month replacement suggestion

The 14 x 17.5 x1.75 MERV 13 two-pack comes from the same third-party seller as the four-pack and shares the same size, MERV 13 rating and six-month replacement advice. The difference is quantity: two filters instead of four. Its listing also names several non-Honeywell dehumidifier models as compatible, which suggests this is a common filter size across whole-home units.

It suits anyone who wants to test a compatible Honeywell DR90 filter before committing to a larger box, or who only replaces once a year. The product dimensions are listed as 17.5 x 14 x 1.75 inches, matching the DR90 and DR120 size. Like the four-pack, this is not a genuine Honeywell part.

Best for
Honeywell TrueDRY DH65 or DR65 owners

The DH65 DR65 Replacement Filter MERV 11 is the Honeywell DH65 filter option in this list, sold by a third-party maker for Honeywell TrueDRY DH65 and DR65 dehumidifiers. The listing names parts 50049537-002/U and 50049537-005, which gives you a clear number to check against your manual.

It is rated MERV 11 for fine particles, dust, pollen, smoke and pet dander, and comes in a four-piece set. Pay attention to the size note: the nominal size is 9 x 11 x 1 inches, but the listing says the actual size is 9 x 11.4 x 0.7 inches. That is normal for filter sizing, but measure your old filter if space is tight. The listing does not give a specific replacement interval, only that you should replace it regularly.

• Listed for Honeywell TrueDRY DH65 and DR65
• Parts 50049537-002/U and 50049537-005
• MERV 11 rating
• Four filters per pack

Best for
HCM-350 style humidifiers, bulk wicks

The Humidifier Replacement Filters A for Honeywell is a third-party version of the Honeywell humidifier wicking filter A, also known as HAC-504. This is a humidifier wick, not a dehumidifier filter, so it only belongs in this guide because people often search for both. The compatibility list is long and includes the HCM-300, HCM-500, HCM-600, HEV-300, HCM-700, HCM-1000 and HCM-2000 series.

The listing describes a multi-layer honeycomb design in rigid absorbent filter paper that resists sagging when wet. The package contains four wicks, and the seller suggests replacing them every two to three months, flipping the filter daily and using distilled water, since hard water causes early yellowing. It suits someone running a Honeywell humidifier in a dry winter gaming room who wants more wicks per box than the genuine three-pack.

Best for
HEV615 and HEV620 tower humidifiers

The Lemige 6 Pack Humidifier Wicking HFT600 is a third-party Honeywell HFT600 filter replacement, also called Filter T. It is listed for Honeywell HFT600T and HFT600PDQ and for the HEV615 and HEV620 top-fill tower humidifiers. Again, this is a humidifier wick and will not fit a dehumidifier.

It uses a honeycomb paper pad for water absorption and comes in a six-pack. The seller recommends replacing each filter every one to two months and flushing and flipping it every time you refill the tank. It suits tower humidifier owners who go through filters quickly.

Genuine wick for HCM-350 style humidifiers

The Honeywell Replacement Wicking Filter A is the only genuine Honeywell part in this roundup. It is the HAC-504 Filter A for evaporative Honeywell humidifiers in the HCM-350, HEV355, HCM-710 and HCM-315/HEV312 series. The listing says it captures minerals in the water and helps reduce white dust, uses a patented design that helps inhibit 99.99% of growth and migration of particles on the filter, and adds a blue pre-filter layer for larger particles.

It comes in a three-pack and measures 5.75 x 5.75 x 9.25 inches. It suits anyone who prefers the genuine part and its pre-filter layer over a larger third-party pack. It gives way to the third-party Filter A if you care more about wick count per box.
