Six American-made filters that capture 98% of airborne particles while keeping airflow resistance industry-leading low.

This BNX 6-pack is the best long-term value for a 16×20 slot if you want maximum coverage with minimum air restriction. The filter media is electrostatically charged polypropylene — not basic fiberglass — which means it zaps particles as small as virus-carriers (0.3 microns) without choking your HVAC system. The maker claims a 98% capture rate at MERV 13, and the MPR 1900 / FPR 10 rating confirms it handles fine smoke and bacteria nearly as well as the Filtrete MPR 2200, but at a lower price per filter when you count the pack.

The frame uses a single-sided one-piece cardboard design that reduces waste, and the filter is manufactured at BNX Converting LLC in Houston, TX (EPA Registration # 101638-TX-1). Buyers report that the 0.75-inch actual thickness slides into 1-inch slots without issue, and many report their energy bills held steady — a sign the low-resistance media is doing its job. Unlike the Filtrete 2-pack above, this six-pack covers a full year of normal use and nearly 18 months if you stick to the 90-day change cycle.

The only trade-off is that the MPR of 1900 is 300 points below the Filtrete 2200, so if you are hyper-focused on trapping the finest smoke particles, the Filtrete still leads on that single spec. But for most homes, the BNX delivers professional-grade filtration with a longer supply and a stronger price-per-filter story.

A reliable 6-pack for larger 16×24 slots with universal fit for Carrier, Bryant, and Honeywell systems.

The Aerostar is the go-to pick if your filter slot measures 16×24 inches — the actual size is 15.75 x 23.75 x 0.75 inches, with an actual size of 15.75 x 23.75 inches compared to 13.5 x 13.5 inches for the 14x14x1 filters. The MPR 1500 / FPR 10 rating means it catches bacteria, smoke, and mold at the MERV 13 level, though the MPR is 700 points lower than the Filtrete 2200 above. For most residential systems and many commercial units, that is still excellent filtration. The heavy-duty beverage board frame with moisture-resistant backing keeps the pleats rigid even in humid basements or crawl spaces — a common failure point with cheaper paper frames that warp and let air bypass the media.

Owners mention that the electrostatic media stays effective for the full 90-day recommended cycle without visible clogging on the face, and the 6-pack covers up to 18 months. One reviewer with a 16×24 slot noted the filter is compatible with Carrier, Bryant, Payne, and Honeywell systems, so you likely won’t run into fit issues. At 1.1 pounds per filter, it feels solid but still light enough to slide in without bending the frame.

The catch is obvious — the Aerostar’s MPR of 1500 is a 47% gap below the Filtrete’s 2200, so homes with heavy smoke or severe allergy needs might prefer the finer capture of the BNX or Filtrete options. But for the 16×24 size, there are fewer multi-pack competitors, and the Aerostar holds its own for general allergen and dust control.

A 6-pack for 14×18 slots that uses 100% synthetic electrostatic media — no fiberglass dust, better capture.

This YEEREAD pack is the first pick if you have a 14×18 slot and want a 6-pack that uses 100% synthetic pleated polypropylene media with electrostatic filtration — the same technology used by premium brands but at a noticeably lower price per filter. The actual size is 13.7 x 17.7 x 0.75 inches, which is a tight fit for nominal 14×18 slots. Customers note that the double-layer cardboard frame with wire mesh keeps the pleats spaced evenly, so the filter surface area stays boost instead of collapsing in on itself like fiberglass filters do.

The filter captures dust, pollen, pet hair, and smoke particles at the MERV 13 level, and the maker recommends changing every 2-3 months — meaning a 6-pack lasts up to 18 months. The clear airflow-direction arrows printed on the frame make installation simple to use: you just line the arrows with the blower direction and slide it in. One buyer mentioned that the electrostatic charge seemed to visibly hold more dust on the face compared to the fiberglass filter they replaced, which directly translates to less dust settling on furniture.

The main limitation is that there is no MPR or FPR number listed in the data — you get a solid MERV 13 rating but no third-party fine-particle score to compare against the BNX or Filtrete. If that level of granularity matters to you, spend a couple extra dollars on a rated option. For the price, this pack is tough to top.

A 6-pack that delivers MPR 1900 performance for 16×25 slots at a price that undercuts the premium names.

This Qingzhug 6-pack punches above its tier for a 16×25 filter slot, matching the BNX’s MPR 1900 and FPR 10 ratings at a lower price per filter. The actual size is 15.75 x 24.75 x 0.75 inches, which fits standard residential 1-inch slots for furnaces, air conditioners, heat pumps, and even air scrubbers and dehumidifiers. The synthetic electrostatic media balances high-efficiency particle capture (dust, pollen, pet dander, smoke) with low airflow resistance, so your HVAC system doesn’t struggle to push air through a dense filter.

Reviewers point out the filters slide into the return vent easily and that the 30-day return and exchange period gives confidence if the fit is off — though most report the actual dimensions match the listed 15.75 x 24.75 perfectly. The recommended change interval is 60-90 days, tightening to every 30 days during peak summer/winter, which means this 6-pack can last anywhere from 6 to 18 months depending on your climate. The filter also works as a 16x25x1 air filter for AC cooling systems without modification.

The downside is that the frame material and brand origin are less established than American-made options like BNX or Aerostar, so if domestic manufacturing is a priority, you might prefer the BNX 6-pack. But on raw specs and pack size, this is a strong value play for 16×25 homes.

A 4-pack of 14×25 filters built in Houston with the same electrostatic media as the bigger BNX packs.

The same BNX electrostatic technology found in the 16×20 six-pack is available here in a 4-pack for the less common 14×25 slot. The actual size is 13.68 x 24.68 x 0.75 inches, comparable with MPR 1500-1900 and FPR 10. The MERV 13 media captures 98% of airborne particles including virus-carriers, bacteria, odors, and smoke, all while maintaining what the maker calls “industry leading low airflow resistance” — a big deal for 14×25 slots where a dense filter can choke the system.

The filter is manufactured at BNX Converting LLC in Houston, TX, an EPA registered facility (# 101638-TX-1), and uses a single-sided one-piece frame made from recycled cardboard to reduce waste. Buyers with 14×25 slots note that the actual fit of 13.68 x 24.68 inches is precise—no gaps around the edges. One reviewer with severe allergies noted less dust on electronics and furniture within two weeks of installation.

The obvious limitation is the pack size: four filters instead of six. At the standard 90-day cycle, a 4-pack lasts 12 months, which is fine for once-a-year ordering but leaves no buffer for peak-season 30-day changes. If you run your system hard in summer and winter, you will run out by month eight. For most casual users, though, a year of protection from a single order is convenient.

The cheapest way to get six MERV 13 filters for a 14×14 slot with a solid MPR 1900 rating.

This Chenzhit 6-pack is the entry-level buy on the list — six MERV 13 filters for a 14×14 slot with an MPR 1900 and FPR 10 rating that punches well above its price tier. The actual size is 13.5 x 13.5 x 0.75 inches, which has an actual size of 13.5 x 13.5 inches compared to the Aerostar’s 15.75 x 23.75 inches, so expect to change this filter slightly more often since the same amount of air passes through a smaller surface. The pleated paper media does the job for dust, pollen, and smoke at the MERV 13 level, and the slide-in mounting fits residential furnaces, air conditioners, heat pumps, and even air scrubbers.

Shoppers say that the filters fit their 14×14 slots snugly with no visible gaps, and the 1-month service period mentioned in the data gives you a month to test the fit and exchange if needed. One owner reported that the cardboard frame is thinner than premium brands, so you should handle the filter gently during installation — a bent frame can create bypass gaps. At this price, the 6-pack still covers 6-18 months depending on change frequency, making it the easiest on the wallet per filter.

The main compromise is the material: paper media rather than synthetic electrostatic polypropylene used by BNX and YEEREAD. Paper is effective at MERV 13 but doesn’t hold an electrostatic charge as strongly, so it relies more on physical interception than on attracting particles. For general home use in a 14×14 slot, it works. For heavy smoke or severe allergy environments, the synthetic options above will capture more fine particles.
