When Should You Replace Your Air Filter?

Most homes replace pleated air filters every 1 to 3 months, but the right schedule depends on your home, air quality needs, pets, and how often your HVAC system runs.

IAQ

Allergies or Air Quality Concerns

Replace every 30 to 45 days

If dust, pollen, or indoor air quality is a concern, check your filter monthly and replace it more often to help keep air moving through clean filtration media.

PET

Pets in the Home

Replace every 2 months

Pet hair and dander can build up quickly. A 2 month replacement schedule is a good starting point for many homes with dogs or cats.

HOME

Standard Home Use

Replace every 2 to 3 months

For homes without pets or major air quality concerns, replacing your filter every 2 to 3 months is a practical starting point.

Quick tip: Check your filter monthly. If it looks dirty, clogged, or restricted, replace it sooner.

MERV Rating Guide

Learn what MERV ratings mean and choose the right level of filtration for your home.

In simple terms, the higher the MERV rating, the smaller the particles the filter can trap. Higher MERV filters can help improve indoor air quality by capturing more dust, allergens, and microscopic particles moving through your HVAC system.

Choosing the right MERV rating depends on your home, allergies, pets, air quality concerns, and HVAC system compatibility.

For a deeper breakdown, read our MERV rating guide to compare MERV, MPR, and APR air filter ratings.

MERV 10

Great for everyday residential filtration and standard home use.

  • Dust and lint
  • Pollen
  • Pet dander
  • Mold spores
  • General household debris

MERV 10 filters offer an excellent balance of airflow and filtration performance for most homes.

MERV 11

Enhanced filtration for homes with pets, allergies, or higher indoor air quality needs.

  • Dust and pollen
  • Pet dander
  • Mold spores
  • Fine household particles
  • Some smoke and smog particles

MERV 11 filters are a popular upgrade for homeowners looking for cleaner indoor air without significantly restricting airflow.

MERV 13

Advanced residential filtration for superior indoor air quality.

  • Fine dust particles
  • Smoke and smog
  • Bacteria carriers
  • Microscopic allergens
  • Some virus carrying particles

MERV 13 filters provide higher efficiency filtration performance for residential HVAC systems and are ideal for allergy sufferers, pet owners, and homes with higher air quality concerns.

Always verify your HVAC system can support higher efficiency filtration before upgrading to a MERV 13 filter.

What MERV Rating Is Best for Me?

A simple guide to choosing between MERV 10, MERV 11, and MERV 13.

The best MERV rating depends on your home, your HVAC system, and how much filtration you want.

Choose MERV 10 if you want a dependable everyday air filter for standard home use and general dust control.

Choose MERV 11 if you have pets, dust concerns, mild allergy concerns, or want a stronger everyday filter.

Choose MERV 13 if you want higher efficiency filtration for smaller particles, smoke, and improved indoor air quality, as long as your HVAC system can handle it.

If you are not sure where to start, MERV 10 and MERV 11 are great choices for many homes. MERV 13 is best for customers who want stronger filtration and have confirmed their system can support a higher efficiency filter.

How Often Should I Replace My Filter?

Replacement timing depends on your home, filter type, and system usage.

Most homeowners replace pleated air filters every 1 to 3 months, but the right schedule depends on your home and how often your HVAC system runs.

You may need to replace your filter more often if you have pets, allergies, heavy dust, recent construction, or your air conditioner runs frequently during warmer months.

Check your filter monthly. If it looks dirty, clogged, or restricted, it is time to replace it.

Wrong item shipped, cost me $30+ to ship back for a product that cost me $89?

Ouch, your mistake cost me $36 to return, how about a return process that doesn't penalize the customer for your mistake - like an RMA number and free shipping when it's your mistake? You took over 3 weeks to ship the wrong product, so I ordered the filters I needed from https://skipthewarehouse.com/ and got the right product from SkipTheWarehouse.com in less than a week.

Won't be buying from this vendor again and will be surprised if I actually get a refund from them... :(

Update 10-10-24: Was pleasantly surprised to receive an apology and refund for the incorrect item from Chad H. at Filters Shipped immediately after leaving this review! Unfortunately, my out of pocket expenses for returning the item ($40.34) via UPS as directed by their website's return policy has yet to be reimbursed, despite Chad H.'s assurance that "As per our return policy, it's never the customer’s responsibility to cover return shipping if the fault is ours." Here is hoping that lightening does strike twice despite the old adage... :)

Damaged filter replaced immediately. Great service!

The 12x24x4 return filter I ordered arrived damaged by the shipper. I contacted the company and another filter was sent out the same day. It was a very easy process and Chad was very helpful. I highly recommend them.

Excellent Customer Service

I placed my first order and was unsure b/c I've never ordered these filters before. However, when I spoke with Chad about my concerns and to confirm that I had ordered the correct filters, he provided excellent customer service. The price didn't disappoint either. I will definitely be ordering from them again.

Filter was only 3.5" thick not 5"

Thank you for your feedback. The filter measures about 3.75 inches thick. It was previously listed as a 5 inch nominal size since Honeywell return grille filters were commonly labeled that way, which helped customers find their size. The actual dimensions are listed on the product page, and we have now updated the listing to show a 4 inch nominal size for clarity.
