MERV stands for Minimum Efficiency Reporting Value — it's a filter rating that shows how well an air filter captures particles from the air.
Higher MERV means better filtration, but it's important to match the best MERV filter for your HVAC system to keep airflow efficient and your air clean. Not sure what to choose? We'll help you find the right fit.
I am so grateful to have found a quality air filter that is just the right size!

Very easy and convenient. FilterBuy even had filter sizes for my furnace unit that I couldn’t find anywhere else. Prices are comparable to what I’d pay for the same filter at the store. With free shipping at my own custom interval, this is really unbeatable. I highly recommend for any homeowner.

HOW TO CHOOSE THE RIGHT FILTER
How do you choose the right filter for your home and family? First you need to understand what your air quality goals are. We have a great video on this if you need help. There are a few things you should know when it comes to choosing an air filter. Do you know your air filter size? What about what type of filter your HVAC system can handle? Here are a few main factors you need to consider when choosing the right air filter for your home:
1. MERV Rating:
Choose a type with a high (Minimum Efficiency Reporting Value) rating. Those that range from 1 to 20, with higher numbers indicate better filtration. For most homes, a rating between 8 and 13 provides a good balance between efficiency and airflow.
2. Filter Size:
Verify if the dimensions properly fit your system. Read your unit's manual for recommended sizes. They will be in standard dimensions such as 16x25x1 or 20x20x1. Incorrect sizing may lead to gaps, reduce effectiveness, and potentially harm your system.
3. Filter Material:
Review the material being used. Most pleated filters, made from polyester or cotton, offer superior filtration and durability.
4. Change Frequency:
Determine how often you need an air filter replacement. Most require changing every 1-3 months, though some can last up to six months.
ONLINE SHOPPING TIPS FOR AIR FILTERS
Shopping online can help you save time and money if you know these tips.
Always know your size. If you don't, we have some guides to help you know what size you'll need.
Measure the length, width, and depth of the current filter to ensure an accurate match. Using the wrong size can lead to inefficiencies and higher energy costs. Many websites provide size charts, so you need to check those too!
After determining the size, consider your budget. However, make sure to look into the long-term benefits of higher-quality filters.
Customer reviews and ratings also provide valuable insights into performance and durability. Look for verified purchaser feedback.

MAINTENANCE TIPS FOR LONGER FILTER LIFE
1. Filter Cleaning
Inspect them regularly for dust accumulation. If washable, rinse them gently with water and ensure complete drying before reinstallation. This step prevents mold growth and keeps airflow efficient.
2. Timely Replacement
Even with thorough cleaning, they require replacement, based on usage and manufacturer guidelines. This practice keeps the heating and cooling unit running efficiently, provides clean air, and minimizes system strain.
3. Inspect Seals And Ducts
Leaks in ductwork introduce additional contaminants, which makes them work harder. Periodically check and seal any gaps or cracks to maintain system integrity.
4. Monitor Air Quality
Use a monitor to assess pollutant levels at home. High levels may necessitate more frequent changes or upgrading to a higher-rated type to capture finer particles.
HOW TO PROPERLY INSTALL YOUR FILTERBUY HVAC FURNACE AIR FILTER
Before you begin, ensure the HVAC system is turned off. This is important for your safety. And to prevent any unfiltered air from circulating while you change the filter.
2. Locate The Compartment
The filter is typically located near the return duct or the blower compartment. In many systems, this will be in the furnace or handler unit.
3. Open The Filter Compartment
You can access it by opening or removing the panel or door covering the filter slot. This may require loosening screws. Or unclipping latches, depending on your unit.
4. Remove The Old One
Carefully slide out the old filter. Take note of the direction of the airflow arrows on the old one if it's still visible.
5. Clean The Filter Slot (Optional)
Use a clean cloth or vacuum to clean the area if there's any dust or debris inside the compartment. Then insert the new filter.
6. Inspect
Remove the new Filterbuy HVAC furnace air filter from its packaging. Check for any visible damage that may have occurred during shipping.
7. Insert The New Filter
Align the airflow arrows on the new one with the direction of airflow in your HVAC system. Typically, the arrows should point toward the blower or the furnace. Slide the new filter into the slot or opening.
8. Secure The Filter Compartment
Once the new one is in place, close the compartment panel or door. And secure it with screws or latches if necessary.
9. Turn On The Air Conditioner
Turn your HVAC system back on after ensuring everything is securely in place.
10. Set A Reminder For The Next Replacement
Depending on the type and your specific needs you should replace them every 1-3 months. Set a calendar reminder to check. Then change as needed.
You can ensure that your Filterbuy HVAC furnace air filter is properly installed and functions effectively by following these steps.
