HPA300 HEPA Filter Replacement for Honeywell

Best for: HPA300 owners wanting filters and pre-filters

Pros

• 6 R-type HEPA filters
• 8 carbon pre-filters included
• H13 True HEPA claim

Cons

• Third-party, not made by Honeywell
• Honeywell warns compatible filters may differ

The HPA300 HEPA Filter Replacement for Honeywell purifiers is a third-party pack from Smilyan, not a Honeywell product. It is built to replace the Honeywell R filter (HRF-R3 and similar) and lists compatibility with the HPA090, HPA100, HPA200, HPA250, HPA300, HPA5200, HPA5300, HPA5350 and HPA8350, among others.

The pack is large: six HEPA R-type filters and eight activated carbon pre-filters, 14 pieces in total. The HEPA filters measure 10.2 by 6.5 by 1.6 inches, and the pre-filter sheet measures 17.2 by 14.2 inches so you can trim it to size. The listing describes an H13 True HEPA filter that captures up to 99.97% of particles, working with the carbon pre-filter, and lists a MERV 17 rating. MERV is a scale for how well a filter catches particles; higher numbers catch smaller ones. These claims come from the seller, not Honeywell.

Honeywell’s own listings warn that compatible filters are not guaranteed to match genuine performance. This pack suits an HPA300 owner who wants years of filters and pre-filters in one order and is comfortable with a non-Honeywell part.

HPA300 HEPA Air Purifier Filter R

Best for: Stocking up on R-type HEPA filters only

Pros

• 6 R-type HEPA filters
• Wide HPA model list
• Replace every 6-12 months

Cons

• Third-party, not made by Honeywell
• No carbon pre-filters included

The HPA300 HEPA Air Purifier Filter R six-pack is a third-party replacement from Cabiclean. It lists a long compatibility range, including the HPA090, HPA094, HPA100, HPA104, HPA200, HPA204, HPA250, HPA300, HPA300VP, HPA304, HPA3300, HPA5300 and HPA8350.

The package contains six HEPA R-type filters only. The seller states clearly that no carbon pre-filters are included, even though another line of the listing talks about the HEPA filter working alongside a carbon pre-filter, so plan to buy pre-filters separately if your purifier uses them. The filters measure 10.2 by 6.5 by 1.6 inches, the listing gives a MERV 12 rating, and the seller suggests replacing them every 6 to 12 months depending on use.

It suits someone who already has pre-filters on hand and just needs to restock the HEPA layer. Buyers who want everything in one box should look at the Smilyan pack above or the genuine Honeywell kit below.

Best for: HPA200 or HPA5200 year-round supply

Pros

• 2 genuine R HEPA filters
• 4 carbon A pre-filters
• Reduces smells and VOCs

Cons

• Fits HPA200 and HPA5200 families only
• Pre-filters need changing every 3 months

Honeywell HEPA Air Purifier Filter R

Best for: A single genuine yearly replacement

Pros

• Genuine Honeywell HRF-R1
• Fits HPA100, 200, 300 series and more
• Light and easy to swap

Cons

• Only one filter
• Pre-filters sold separately

Best for: Three years of genuine R filters

Pros

• Genuine Honeywell R filter
• Captures 99.97% of listed allergens
• 3-pack covers yearly changes

Cons

• Pre-filters sold separately
• Spec line lists only HPA5300

The Honeywell HEPA Air Purifier Filter R three-pack is the genuine article. Honeywell says it is designed exclusively for the HPA094, HPA100, HPA200, HPA250, HPA300, HPA3100, HPA3300, HPA5100, HPA5200, HPA5300 and HPA8350 series. One specification line lists only the HPA5300, but the feature list and description name the full range.

Honeywell says these filters help capture 99.97% of airborne dust, pollen, pet dander, dust mite debris and smoke, and that a purifier with a certified Honeywell filter circulates air up to 4.8 times an hour in the stated room size. Honeywell recommends replacing the HEPA filter once a year, so a three-pack lasts about three years in one purifier. Pre-filters are sold separately. The specifications list a MERV 16 rating and a fiberglass pleated construction.

This pack suits a long-term owner who wants the genuine filter and no reorders for a while. If you are still choosing a machine, our guide to Honeywell air purifiers for home explains the models.

The Honeywell HEPA Air Purifier Filter R single pack (model HRF-R1) is one genuine R filter. It shares the same compatibility list and claims as the three-pack: the HPA094 through HPA8350 series, 99.97% capture of the listed allergens, up to 4.8 air changes an hour and a yearly replacement schedule. Pre-filters are sold separately.

It measures 6.69 by 1.65 by 10.32 inches and weighs about 4 ounces. Larger console purifiers can hold more than one R filter at a time, so check your manual for how many your model needs before ordering a single filter.

This option suits a first-time owner doing their first yearly swap, or someone testing whether the purifier is worth keeping before buying multiples.

Best for: Small HPA020 to HPA180 series purifiers

Pros

• Genuine Honeywell G filter
• Two filters for two years
• 97% at 0.3 microns

Cons

• Does not fit R-filter models
• No pre-filter included

The Honeywell Genuine HEPA Air Purifier Filter G two-pack is for a different family of machines. It fits the HPA020, HPA030, HPA075, HPA080, HPA175 and HPA180 series, which are smaller units. It will not fit R-filter purifiers such as the HPA300.

Honeywell says the G filter captures up to 99.97% of airborne particles at 0.3 microns from the air that passes through it. A micron is one-thousandth of a millimeter, and 0.3 microns is the standard test size for HEPA filters. Each filter measures 5.12 by 1.5 by 10.24 inches, and the pack weighs 7.12 ounces. Replace once a year, so two filters last two years.

This pack suits owners of Honeywell’s compact purifiers in bedrooms or offices. For more on keeping indoor air fresh in small spaces, see our air purifier filter replacement guide.

The Honeywell HEPA Air Purifier Filter Kit is a genuine one-year supply for the HPA200, HPA201, HPA202, HPA204, HPA250, HPA3200 and HPA5200 series. It includes two Honeywell R HEPA filters and four pre-cut A carbon pre-filters.

The A pre-filters catch larger particles before they reach the HEPA filter, and their activated carbon reduces unpleasant smells and VOCs (volatile organic compounds, the gases released by paints, cleaners and cooking). Honeywell recommends changing pre-filters every three months and HEPA filters once a year, which is why the kit pairs four pre-filters with two HEPA filters.

It suits HPA200 and HPA5200 owners who want genuine parts and a simple once-a-year order. It is not listed for the HPA300, so HPA300 owners should use the R filter packs above.
