Choosing the Correct Filter Size 
Nominal Size vs. Actual Size
The nominal size is a shorthand number rounded to the nearest whole or half inch, normally in a larger font (ex: 16 x 20 x 1). Whereas the actual size is an exact measurement, normally in a smaller font, that depicts the filter’s precise dimensions (ex: 15.50 x 19.50 x 0.75). All filters have both.

Measuring Your Air Filter
If your current air filter does not have a dimension listed on the frame, use a tape measure to record the width x length x depth to find the actual size. Then round these measurements up to the nearest inch to find a corresponding nominal size, which will be easier to locate when searching online.
Why should I change my air filter?
To maintain a healthy lifestyle, as breathing dirty air can put you at risk to develop asthma, allergies, and other respiratory ailments. Plus, old filters can cause system defects which may lead to unwanted expenses via energy costs and repairs.
When should I change my air filter?
We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean. But this is subject to change based on filter size and variable factors for pet owners, allergy sufferers, homes with children, etc.
Will these air filters fit my system?
Most of our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system as long as you choose the proper size. But if you see a specific brand name on a listing, make sure it matches your unit model.
How many air filters do I need?
This varies for every customer depending on specific needs such as the number of vents in your home. However, our selection includes package quantities that range from 1 to 12 filters, so no matter what your situation may be, we’ve got you covered.
How do I change my air filter?
After finding the right size, turn off the power supply and remove the cover from your intake vent before taking out the old filter. Then just insert your new filter to match the direction of air flow, replace the cover, and turn the power back on.

Great if you recieve to correct product…
On my first order, they sent me not only the wrong product. It was the wrong size, the wrong filter quality, and also the wrong package size! They got everything wrong.Unfortunately, in order to get the proper item shipped to me, they needed to receive the wrong item first before shipping the correct item. Very upsetting. So I ended up just ordering the product again hoping I would get the correct one this time and just requested a refund upon return of incorrect item. I was refunded promptly once they received the wrong product.Luckily, they sent the correct product the second time around. The filter works great and fits perfectly. I do plan to continue to order this product.

Reliable High-Filtration Air Filter I Repurchase Every Two Months
I’ve been purchasing the Filterbuy 16x36x1 Air Filter (MERV 13, Optimal Smoke) consistently every two months, and it has become my go-to choice for maintaining indoor air quality.The filter fits true to size and installs easily. Despite the higher MERV rating, airflow remains strong while effectively capturing smoke, dust, and fine particles. Each time I replace it, there’s visible buildup on the filter, which confirms it’s doing exactly what it’s designed to do without stressing my HVAC system.Pros:• Consistent, true-to-size fit• Excellent filtration for smoke and fine particles• Maintains good airflow for a MERV 13 filterCons:• Requires more frequent replacement than lower MERV options• Costs more than basic filtersValue for money:Given its reliable performance and high level of filtration, it’s a good value and worth the recurring purchase for cleaner air.Overall, this is a dependable filter I trust enough to buy on a regular schedule,

These are shipped from the USA. I wish they were shipped in a stronger ship box.The flimsy shipping box was damaged and had a little damage to the one cornerof the internal furnace filter. It was still useable. I decided to not return.Excellent filters.
