Filtrete 14x25x1 AC Furnace Air Filter MERV 13 - Premium Allergy

Our review of the Filtrete 14x25x1 AC Furnace Air Filter finds it best for homeowners who want stronger particle capture without sacrificing airflow. This 6-pack of 3-month pleated 1 in filters is aimed at families and allergy sufferers who need a higher-performance residential filter: it combines a MPR 1900 rating and MERV 13 performance to trap many microparticles while allowing HVAC systems to run efficiently. For those who prioritize cleaner indoor air and certified asthma-and-allergy-friendly components, this filter is a practical upgrade over basic pleated filters.

Key Features

• Exact fit: The filters measure 13.81 x 24.81 x 0.78 in so you know the true size before installing and can avoid surprises with nominal sizing.
• High particle capture: A 1900 MPR and MERV 13 rating captures up to 62% of small particles between 0.3 and 1 micron, helping reduce bacteria and particles that carry viruses.
• 3-in-1 technology: Filtrete's exclusive electrostatic design pulls in and traps a wide range of particles from lint and pollen to smoke and pet dander.
• Certified for allergies: This filter is certified asthma-and-allergy-friendly, making it a sensible choice for sensitive households.
• Better airflow claim: Filtrete MPR 1900 filters are designed to deliver higher airflow than other residential MERV 13 1 in filters, supporting system efficiency.
• Smart reminders: Use the Filtrete Smart App to set a 30-, 60- or 90-day reminder so you change filters on schedule for optimal performance.

Who It's For

This filter is ideal for homeowners with central furnaces or HVAC systems who want to step up from basic filters to something that traps finer particles. Allergy sufferers, households with pets, and anyone concerned about smoke or city smog will see clear benefits from the MPR 1900 filtration and the asthma-and-allergy-friendly certification.

It is not aimed at commercial installations or systems that require thicker or specialty filters; if an HVAC system specifies a thicker filter than 1 in or requires a different MERV rating for warranty reasons, buyers should choose a filter that matches those requirements.

Pros & Cons

Pros

• Effective at removing fine dust, pet dander and smoke thanks to the high MPR and MERV 13 rating.
• Certified asthma-and-allergy-friendly, offering reassurance for sensitive occupants.
• Designed to maintain good airflow compared with many other residential MERV 13 1 in filters.
• Six filters per pack provides convenient quarterly replacements for multiple vents or an extended supply.

Cons

• Actual longevity can vary; some users report replacement closer to two months in heavy-dust or wildfire conditions rather than the recommended 90 days.
• Slightly smaller than nominal 14 x 25 x 1 sizing, so check the exact 13.81 x 24.81 x 0.78 in dimensions before ordering.

Frequently Asked Questions

Will this filter fit my 14 x 25 x 1 slot?
Check the filter slot and compare to the actual dimensions of 13.81 x 24.81 x 0.78 in to ensure a proper fit, since this differs from the nominal size.

How often should I change the filter?
Filtrete recommends changing every 90 days, but heavy use, pets, or wildfire smoke can require replacement closer to every 60 or 30 days.

Does it reduce allergens and bacteria?
Yes, the MPR 1900 and MERV 13 ratings plus certification for asthma and allergy friendliness mean it helps capture allergens, bacteria and many particles that carry viruses.
