If you own a PuroAir purifier and your filter light is on, the first thing to know is that “HEPA 14 filter” is not one universal part. The replacement you need depends on which unit sits in your game room: a Puro Air 240 and a Puro Air 400 take different filters, and they are not interchangeable. The second thing to know is that the three options in this guide are not all the same kind of product. Two are compatible third-party purifier filters, and one is a PuroAir-branded HVAC furnace filter that goes into your home’s air system, not into a purifier at all.
This PuroAir filter comparison covers those three products: a 4-pack of Puro Air 240 compatible filters, a 2-pack of Puro Air 400 compatible filters, and the PuroAir MegaFilter 14x14x1 MERV 13 furnace filter. We compared listings and specifications, not our own lab results. We also point out a key gap: neither compatible purifier filter listing states a HEPA grade, including H14, so if that certification matters to you, check before you buy.

Best for
Puro Air 240 owners stocking up
Pros
- Four filters per pack
- Pre-filter, main and carbon layers
- 4-8 month replacement guidance
Cons
- Third-party, not OEM
- HEPA grade not stated
The 4 Pack 240 Replacement Filter Compatible with the Puro Air 240 is sold by PAYUDAL, not by PuroAir. The listing says so directly: it is not an OEM product, and the Puro Air name appears only to show compatibility. It also states it fits only the Puro Air 240 purifier. That honesty is helpful. You know what you are buying, and you should not expect it to carry any PuroAir filter certification or warranty.
Each filter uses a three-stage design: an ultra-fine pre-filter to catch larger particles, a main filter made of woven micron-level fibers in a high-density, low-resistance structure, and a high-efficiency activated carbon filter for odors. The listing specs give a MERV 12 rating, pleated filter paper construction and dimensions of 7.48 by 6.3 by 7.48 inches, with filters made of FSC-certified paper. It does not claim a HEPA grade such as H13 or H14. PAYUDAL recommends replacing it every 4 to 8 months depending on air conditions and how often you run the purifier.
The four-pack is the main appeal. If your 240 runs all day in a closed game room with a warm PC and a pet or two, you may land at the shorter end of that interval, and four filters could cover a long stretch before you reorder. If you want an official Puro Air 240 replacement filter with a stated HEPA grade, this is not it.
- Fits only the Puro Air 240 purifier
- Pre-filter, main filter and activated carbon layers
- Four filters per pack
- Replace every 4 to 8 months, per the listing

Best for
Puro Air 400 owners needing spares
Pros
- Two filters per pack
- 3-in-1 with activated carbon
- 6-8 month replacement guidance
Cons
- Third-party, not OEM
- Listing omits dimensions
The 400 Replacement Filter for Puro Air 400 comes from the same seller, PAYUDAL, and follows the same approach. It is not an OEM product, and the listing states it is compatible only with the Puro Air 400 purifier. Do not try to use it in a 240 or vice versa.
The construction mirrors the 240 version: an ultra-fine pre-filter, a main filter of woven micron-level fibers, and a high-efficiency activated carbon layer. The listing highlight says it targets air particles, pet dander, smoke and odors. You get two filters per pack, made from FSC-certified filter paper, with a recommended replacement window of 6 to 8 months. The listing does not specify dimensions, MERV rating or HEPA grade.
For a larger purifier covering a living room or basement gaming setup, two spares give you roughly a year of coverage at the listed interval. As with the 240 filter, if you need a specific HEPA certification, check the original manufacturer’s filter.

Best for
Homes with 14x14x1 HVAC returns
Pros
- MERV 13 with active carbon layer
- Made by PuroAir
- Slide-in install
Cons
- HVAC filter, not for purifiers
- Actual size 13.75 x 13.75 x 0.75 in
The PuroAir MegaFilter 14x14x1 Air Filter MERV 13 is the only PuroAir-made product here, and it is not a purifier filter. It is a 2-pack of HVAC furnace filters for air conditioners and furnaces that take a 14x14x1 filter. The actual size is 13.75 by 13.75 by 0.75 inches, which is normal for nominal filter sizes, and PuroAir says it slides in within about 30 seconds.
It uses a three-layer design: a pre-filter, a MERV 13 filter and CarbonTech active carbon. PuroAir says, based on independent lab testing and typical MERV 13 and active carbon performance, that it is four times more efficient than lower-grade filters for particles of 1 to 3 microns and lasts three times longer than traditional fiberglass filters. It targets allergens, pet dander, smoke and odors. The material is electrostatically charged polypropylene with a proprietary activated carbon blend, in a pleated build.
Why is it in a HEPA 14 roundup? Because many people searching for PuroAir filters are really trying to clean the air across a whole home. A MERV 13 furnace filter works on every room your system serves, including the game room, while a purifier works harder on one room. If your system uses a 14x14x1 slot, this is a smart complement to a purifier, not a replacement for one.
- MERV 13 with pre-filter and active carbon
- Actual size 13.75 x 13.75 x 0.75 inches
- Two filters per pack
- Fits air conditioners and furnaces, not purifiers

NOTES
Buying Tips for PuroAir Filters
Confirm your model before you buy. Look at the label on the purifier or in the manual for 240 or 400, and match it exactly. Compatible filters are cut to fit one model, and a filter that does not seal properly lets air bypass the media, which defeats the point. For HVAC filters, check the size printed on the frame of your current filter rather than measuring the slot.
Understand what the grades mean. HEPA grades such as H13 and H14 describe purifier filter efficiency on very fine particles, while MERV ratings describe HVAC filter performance. They are different scales for different systems. Neither compatible purifier filter here states a HEPA grade, so treat them as three-stage filters with carbon rather than certified H14 media. If you are shopping for a smaller purifier for a bedroom setup, our guide to a compact HEPA air purifier explains what to look for.
Put replacements on a schedule. A gaming room with the door closed, warm hardware and long sessions tends to load filters faster than a spare bedroom. Mark a calendar reminder at the short end of the listed interval, and swap sooner if the carbon layer stops handling odors. Our broader guide to air filter replacement habits covers signs that a filter is spent.
