Top Takeaways
Fit matters more than brand. Our 16x25x5 filters match OEM specs—without the markup. Verify your dimensions before ordering.
MERV 11 is the sweet spot. Captures allergens without restricting airflow. MERV 13 only if your system supports it.
Clean filters save money. A fresh filter cuts energy use by 5–15% and protects your $5,000+ system.
Indoor air needs attention. You spend 90% of your time indoors, where pollutants run 2–5x higher than outside.
Consistency beats intensity. A MERV 8 changed every 90 days outperforms a neglected MERV 13. We've seen it countless times.
How to Confirm You Need a 16x25x5 Filter
Before ordering, pull your current filter and check the dimensions printed on the frame. You're looking for a nominal size of 16x25x5—which translates to actual dimensions of approximately 15.75" x 24.75" x 4.38". We include both nominal and actual measurements on every product page because this mismatch causes more returns industry-wide than any other issue.
If your filter cabinet is built into a Maytag air handler or furnace, the 16x25x5 is one of the most common deep-pleated sizes the brand uses. No filter installed currently? Measure the cabinet opening itself—length, width, and depth—and compare against our specs.
Maytag Systems: This Filter Fits
Our 16x25x5 compatible filter is engineered as a direct replacement for Maytag MACA16x25x5, MACB16x25x5, and similar part numbers. We've cross-referenced these against the most common Maytag HVAC configurations to ensure drop-in compatibility without modifications.
Customers frequently ask whether aftermarket filters perform as well as OEM. Our answer: the filtration media and frame construction meet or exceed original equipment standards. The difference is we cut out brand licensing costs and manufacture directly, passing those savings to you.
Choosing the Right MERV Rating
We offer this size in MERV 8, MERV 11, and MERV 13 options—each balancing filtration efficiency with airflow differently:
MERV 8 captures dust, pollen, and lint. Ideal for homes without allergies or pets, and easiest on your system's blower motor.
MERV 11 adds protection against pet dander, mold spores, and finer dust particles. Our most popular choice for households with animals or moderate allergy concerns.
MERV 13 filters bacteria, smoke particles, and microscopic allergens. Best for respiratory sensitivities, but confirm your system supports the increased resistance.
Not sure which to pick? Start with MERV 11. It's the sweet spot we recommend most often based on customer feedback and performance data.
Built for a Precise Fit
Fit problems stem from two sources: incorrect dimensions and flimsy construction. We address both. Our 16x25x5 filters use a rigid beverage-board frame that holds its shape during installation and won't compress over time. The pleated media sits flush within the cabinet, creating a reliable seal against the housing.
We've tested these filters across dozens of Maytag system configurations. They slide in without force, sit flat without bowing, and leave no gaps around the edges where unfiltered air could slip through.
Why Customers Switch to Filterbuy
OEM replacements typically cost 30–50% more and ship from limited distribution channels. We manufacture in-house, maintain consistent inventory, and ship direct—often next day. Subscribers save an additional 5% and never miss a filter change with scheduled deliveries.
Still uncertain about fit? Our customer service team can verify compatibility using your Maytag model number before you order.
"After manufacturing millions of 16x25x5 filters and hearing from thousands of Maytag system owners, we've learned that fit and filtration consistency matter more than brand names—which is exactly why we engineer every filter to match OEM specs without the OEM markup."

Supporting Statistics
We don't ask customers to take our word for it. The federal data backs up what we've observed after manufacturing millions of filters.
Indoor Air Is Dirtier Than Most People Realize
Customers often assume outdoor air is the problem. The EPA data surprises them:
Indoor pollutant concentrations run 2 to 5 times higher than outdoor levels
Americans spend approximately 90% of their time indoors—roughly 21 hours daily
Your HVAC filter is the primary defense for the air you're constantly breathing constantly
We've seen this firsthand. Customers send us photos of filters pulled after just 60 days—the buildup tells the story.

Clean Filters Lower Energy Bills
The Department of Energy confirms what our subscription customers report regularly:
Replacing a clogged filter reduces energy consumption by 5% to 15%
Heating and cooling account for nearly 50% of home energy costs
A $30 filter protects a $5,000+ HVAC system from premature failure
Consistent 90-day replacements pay for themselves. Neglected filters lead to emergency repairs.

Allergies Drive Most MERV Upgrade Decisions
When customers call about MERV ratings, allergy concerns lead the conversation. The numbers explain why:
81 million Americans are diagnosed with seasonal allergic rhinitis
Affects roughly 1 in 4 adults and 1 in 5 children
Most sufferers spend 90% of their time where allergens accumulate—indoors
What we've learned: Upgrading from MERV 8 to MERV 11 or 13 makes a noticeable difference for most allergy households.

Final Thought: Why We Recommend Starting With Fit—Then Filtration
After manufacturing millions of 16x25x5 filters and helping thousands of Maytag system owners, we've learned something that surprises most customers: filter brand matters far less than fit and replacement consistency.
Here's our honest take.
OEM filters aren't magic. They're manufactured to a specification—the same specification we engineer our compatible filters to match. We cut out the brand licensing markup and ship directly. Identical performance. Lower price. Faster availability.
What actually matters:
Correct dimensions — A filter that's too small lets unfiltered air bypass the media. Too large and it won't seat properly. Your 16x25x5 nominal size must match your cabinet exactly.
Appropriate MERV rating — Higher isn't always better. MERV 13 captures more but restricts airflow. Most households land at MERV 11 as the practical sweet spot.
Consistent replacement schedule — A MERV 8 changed every 90 days outperforms a MERV 13 left in for six months. We've seen more HVAC damage from neglected filters than any other single cause.
The customers who get the best results:
Verified their dimensions before ordering
Selected a MERV rating appropriate for their household
Committed to regular changes—subscription or calendar reminders
Still uncertain about fit or filtration level? Our team can verify compatibility using your Maytag model number before you order. We'd rather answer questions upfront than process returns later.
That's how we've built a business on replacements and referrals—one correctly fitted filter at a time.
Frequently Asked Questions
Q: How do I know if a 16x25x5 filter fits my Maytag system?
A: This is our most common question. Check your current filter's frame for printed dimensions:
Nominal size: 16x25x5
Actual size: 15.75" x 24.75" x 4.38"
Our filters fit Maytag systems using MACA16x25x5, MACB16x25x5, and similar part numbers. If your existing filter shows 16x25x5, ours will slide right in.
Still uncertain? Send us your Maytag model number. We verify compatibility daily.
Q: Are Filterbuy's Maytag compatible filters as good as OEM?
A: Yes. Here's what most customers don't realize:
OEM filters aren't manufactured by Maytag—they're made by filter companies and branded for resale
We manufacture to the same specifications in our own facility
We skip brand licensing fees and sell directly
After producing millions of 16x25x5 filters, we're confident: performance is identical. Price isn't—OEM typically costs 30–50% more.
Q: What MERV rating should I choose for my Maytag system?
A: Most customers overthink this. Here's our guidance:
MERV 8 — Everyday dust and pollen. Homes without pets or allergies.
MERV 11 — Pet dander, mold spores, finer particles. Our bestseller by a wide margin.
MERV 13 — Smoke, bacteria, microscopic allergens. Restricts airflow more.
We've talked customers down from MERV 13 when their systems couldn't handle the resistance. Our recommendation? Start with MERV 11 unless you have specific respiratory concerns.
Q: How often should I replace my 16x25x5 Maytag compatible filter?
A: Every 90 days for most households. Adjust based on your situation:
60 days — Multiple pets, allergy sufferers, heavy HVAC usage
90 days — Standard households
120 days — Minimal usage, no pets
Here's what we've learned: consistency matters more than MERV rating. A MERV 8 changed on schedule outperforms a neglected MERV 13. That's why we built our subscription program—filters arrive automatically, so the decision is made for you.
Q: What if the filter doesn't fit my Maytag system?
A: Fit problems are rare. We've kept our return rate under 2% by verifying dimensions upfront.
