Good Air Filters for Home: MERV 11 vs MERV 13 Furnace Picks

The good air filters for home use are 1-inch pleated furnace filters rated MERV 11 to MERV 13: they trap much of the dust, pollen and pet dander that circulates through your heating and cooling system without choking airflow in most homes. Our top pick for typical households is the Filtrete MERV 13 (MPR 1900) in a 16x25x1 size, and the budget runner-up is the BNX TruFilter or Filterbuy MERV 13 in multi-packs. If your system is older or struggles with airflow, step down to MERV 11, such as the Honeywell 20x25x1 MERV 11 or the Filtrete MERV 11 (MPR 1000). Always confirm your exact size first, because the best filter is the one that fits and that you actually replace.

This guide is research-based. We compared manufacturer specification pages, filter ratings from industry standards, and product listings. We did not personally use these products. Sizes below are common examples (16x25x1 and 20x25x1); the same brands sell dozens of other sizes, so measure the filter you have now. Anything the maker does not state is marked “not listed”.

Comparison Table

What “Good” Means for a Home Air Filter

An in-home air filter is the pleated panel that slides into your furnace or air handler. Every bit of air your system moves passes through it, so it protects the equipment and also catches airborne particles. A good one balances three things: capture efficiency (MERV), airflow resistance, and replacement habits.

MERV (Minimum Efficiency Reporting Value) is a 1-to-20 scale for how well a filter captures particles of different sizes. A rough guide, based on the ASHRAE standard, is:

The U.S. EPA suggests using a filter rated MERV 13 or better if your system can handle it, and many HVAC pros agree that MERV 11 to 13 is the sweet spot for homes. Filters labeled “MPR” (Filtrete) or “FPR” (another retail scale) are brand-specific scales: MPR 1900 roughly corresponds to MERV 13, and MPR 1000 to MERV 11.

Check Your System Before You Buy MERV 13

The higher the MERV, the more resistance air faces. Many modern systems handle MERV 13 without a problem, but older or undersized blowers can lose airflow, which can lead to frozen coils or reduced comfort. Check these before upgrading:

• Look at the data plate or manual for the maximum MERV the system supports.
• If you cannot find it, start with MERV 11 and watch for weak airflow at vents or longer run times.
• Replace the filter on schedule. A loaded MERV 13 filter restricts airflow far more than a fresh MERV 8.
• If your system is not designed for high-MERV filters, add a portable air purifier in the main living area instead of upgrading the furnace filter.

Sizing: The Number on the Edge

Filters are sold by nominal size such as 16x25x1 and 20x25x1, but the actual size is slightly smaller. For example, Filterbuy lists 15.50 x 24.50 x 0.75 inches for a 16x25x1, Aerostar lists 15.75 x 24.75 x 0.75, and Filtrete lists 15.62 x 24.62 x 0.78. Always buy the nominal size printed on the old filter’s cardboard frame. If it says 16x25x1, any brand’s 16x25x1 will fit. Don’t trim a larger filter to fit, because gaps let unfiltered air bypass the media.

1. Filtrete 16x25x1 MERV 13 (MPR 1900): Best Overall

• MERV 13, MPR 1900
• Actual size 15.62 x 24.62 x 0.78 inches
• Marketed for allergens, bacteria, viruses and air pollutants
• Designed as a 3-month AC and furnace filter; sold in 2-pack and 6-pack counts

Best for: households with allergies that want a mainstream, easy-to-find filter. Skip if: your blower is old or you often forget to change filters.

Filtrete is the filter many homeowners reach for because it is stocked everywhere and the MPR scale is printed on the front. The 1900 rating is the brand’s top consumer tier for standard 1 inch filters, and independent summaries equate it to MERV 13. The listing claims capture of allergens, bacteria and viruses, but those are marketing categories; treat them as indications of the particle size range rather than health promises.

The 3-month rating is the maximum. In a home with pets or during wildfire or pollen season, replace it every 60 days, or check it monthly. The pack sizes make it easy to buy a year’s supply, and a calendar reminder on the same date each season is the most reliable habit you can build.

Pros: widely available; clear rating; multiple pack sizes. Cons: higher airflow resistance than MERV 11; more expensive per filter than some multi-packs.

2. BNX TruFilter 16x25x1 MERV 13: Best Value in Multi-Packs

• MERV 13, MPR 1900 and FPR 12 on the listing
• Electrostatic pleated media, “Smoke, Allergy, Pet Defense”
• Actual size 15.69 x 24.69 x 0.75 inches
• Made in USA; 4, 6 and 12 pack options

Best for: homeowners who want a whole year’s filters in one box. Skip if: you only need a single trial filter.

The TruFilter targets the same MERV 13 level as Filtrete but is usually sold in larger bundles, which lowers the cost per filter and reduces the chance of running out. The listing shows three rating scales (MERV, MPR, FPR), which helps if you are comparing across brands. A 12-pack covers a year at one change per month, a 6-pack covers a year at one change every two months.

Electrostatic media holds particles with a light static charge. Its performance can fade as the filter loads, which is another reason to replace on schedule.

Pros: several pack sizes; made in USA; multiple rating scales; pet and smoke positioning. Cons: upfront cost of a large pack; high MERV may not suit every system.

3. Filterbuy 16x25x1 MERV 13: Best Made-in-USA Smoke and Allergy Filter

• MERV 13, “Smoke and Allergy Defense”
• Electrostatic pleated
• Actual size 15.50 x 24.50 x 0.75 inches
• Made in USA; 4-pack and 6-pack

Best for: homes affected by wildfire smoke seasons and indoor smoke odors. Skip if: your housing has a tight filter slot that needs the full nominal width.

Filterbuy’s actual width is half an inch less than the nominal 16 inches, which is typical but can leave a small gap in a loose filter rack. Check that the frame sits snugly against the slot; if you see light around the edges, air is bypassing the media. As with all MERV 13 filters, make sure your system tolerates the airflow resistance.

Pros: made in USA; smoke and allergy positioning; pack options. Cons: slightly smaller than nominal; same airflow caution as other MERV 13s.

4. Honeywell 20x25x1 MERV 11: Best Airflow-Friendly Option

• MERV 11, “Allergen Reducer 11000”
• Electrostatic pleated, 4-pack
• Made in USA; marketed as a replacement for home use

Best for: older systems, dusty homes and pet owners who want better filtering than basic MERV 8 without the resistance of MERV 13. Skip if: you need the highest capture rate for smoke or fine particles.

MERV 11 sits in the middle of the range and is frequently recommended by HVAC contractors as a safe step up. It catches finer dust, pet dander and many mold spores while keeping airflow relatively open. If you have noticed that a MERV 13 filter makes the system sound strained, MERV 11 is the sensible fallback. The listing does not list actual dimensions in the text we reviewed, so check the product page against your frame.

Pros: easier on airflow; well-known brand; pack of four. Cons: lower fine-particle capture; actual size not listed in our source.

5. Filtrete 20x25x1 MERV 11 (MPR 1000): Best Mainstream MERV 11

• MERV 11, MPR 1000
• Actual size 19.68 x 24.68 x 0.81 inches
• Marketed for allergens and pet dander; 3-month filter
• 2, 4 and 6 pack options

Best for: pet households with systems that prefer lower resistance. Skip if: you need MERV 13 for smoke season.

This is the same family as the MERV 13 pick with a lower rating. The actual thickness is 0.81 inch, slightly deeper than many brands at 0.75 inch, so check that it slides in without bending. The listing positions it for allergens and pet dander at a more forgiving airflow cost.

Pros: easy to find; many pack sizes; gentler on airflow. Cons: less capture of the finest particles; slightly deeper frame.

6. Aerostar 16x25x1 MERV 13: Best Budget Multi-Pack

• MERV 13, 6-pack
• Actual size 15.75 x 24.75 x 0.75 inches
• Listed for allergies, dust, pet dander and smoke

Best for: filter change routines where cost per filter matters. Skip if: you want a more familiar premium brand.

Aerostar sells a variety of MERV 8, 11 and 13 filters. The MERV 13 version in a 6-pack gives a clear cost-per-change advantage. The actual dimensions are the closest of our picks to the nominal size, which can help in a snug frame. Other listings, such as the Aerostar 20x25x1 MERV 11, show a rating of MPR 1200 and FPR 7.

Pros: multi-pack value; close to nominal size; MERV 13. Cons: less brand recognition; claims are the maker’s.

How We Chose

We started with the filters most homeowners can actually buy, in the two most common residential sizes. We compared MERV and brand rating scales, actual dimensions, pack sizes and country of manufacture where listed, using manufacturer product pages, industry standards summaries and guidance from the U.S. EPA and ASHRAE. We did not personally use these products and did not run airflow measurements. We limited the list to two models per brand and included both MERV 11 and MERV 13 so you can match the filter to your system. If a listing did not show a detail such as exact dimensions, we wrote “not listed”.

Buying Guide

Start with the size

Pull your current filter and read the nominal size on the frame. Measure the slot if the frame is worn. If the system uses a deeper cabinet (4 or 5 inches), you need a different filter type entirely; a 1-inch filter will not seal.

Pick the MERV for your system

Use MERV 8 to 11 for older or restricted systems, MERV 11 to 13 for modern systems and homes with pets or allergies, and MERV 13 where smoke or fine particles are a priority. If you hear the system working harder or airflow drops after a change, step down one level.

Plan your replacement schedule

The worked math is simple: a 90-day filter needs 4 changes per year, a 60-day schedule needs 6, a monthly schedule needs 12. Buying a pack sized to your schedule avoids running out. For example, two cats and a dog usually justify the 60-day schedule, so a 6-pack covers the year.

Consider electrostatic vs. standard pleated

Electrostatic filters use a static charge to capture particles. They are common in consumer packs and can perform well when new. Standard pleated filters rely on fiber density. Neither replaces timely changes.

Add a portable purifier if needed

A furnace filter only works while the blower runs. If you want cleaner air in a bedroom all night, a room air purifier with HEPA filtration complements the furnace filter.

Common Mistakes

• Buying MERV 16 for a standard residential system. It may choke airflow.
• Leaving a filter in too long. A clogged filter lowers airflow and efficiency.
• Installing the filter backward. Follow the airflow arrow on the frame toward the blower.
• Ignoring gaps around the filter. Seal gaps in the rack so air does not bypass the media.
• Mixing up nominal and actual size. Buy by the nominal size printed on the frame.

Frequently Asked Questions

What is a good air filter for home use?

A pleated MERV 11 to MERV 13 filter in the correct size is a good choice for most homes. MERV 13 offers stronger capture of fine particles, while MERV 11 is easier on airflow.

Is MERV 13 too restrictive for my furnace?

Not for most modern systems, but older or underpowered blowers can struggle. Check your equipment manual or ask an HVAC technician, and change filters on schedule.

How often should I change a 1 inch furnace filter?

Most makers suggest every 90 days. Change it every 60 days or sooner with pets, smoke or construction dust, and check it monthly.

Does a better filter help with allergies?

A higher-MERV filter can reduce airborne particles such as pollen and pet dander that pass through the system, which may help comfort. It is not a medical treatment, so talk to your doctor about your symptoms.

What does MPR mean on Filtrete filters?

MPR is the brand’s Micro Particle Performance Rating. A higher number means better capture of small particles. MPR 1900 is generally equated to MERV 13 and MPR 1000 to MERV 11.

Can I use a thicker filter?

Only if your cabinet is built for it. A 4 inch or 5 inch media cabinet holds a deep filter; a 1 inch slot does not. Thicker filters often last longer and restrict airflow less.

Are washable filters a good alternative?

Washable filters can save money but usually have lower MERV ratings and must be fully dry and clean to avoid mold. Most people looking to reduce allergens choose disposable pleated filters.

Which One Should You Buy?

If your system is modern and you want the strongest mainstream option, buy the Filtrete MERV 13 in your size. If you want to buy a year’s supply at once, choose the BNX TruFilter or Aerostar multi-pack. If smoke is a concern, the Filterbuy MERV 13 is a good fit. If you have an older system or notice airflow problems, step down to Honeywell or Filtrete MERV 11. Whichever you choose, confirm the nominal size, mark the replacement date on the frame and keep a spare filter on hand.
