Cleaning of indoor air is essential for health and comfort. The air filter 17.25x26x2 from Filterbuy captures dust, pollen and other airborne particles. This filter was designed to perform well and last long. It cleans the air without restricting airflow.
In this guide, you’ll learn how to install your filter properly and understand what makes it unique.
Use the exact air filter size. Filterbuy air filter 17.25x26x2 ensures proper fit and airflow.
Pick the correct MERV rating. Filterbuy filters provide MERV ratings 8, 11 and 13 for allergies, pets or finer particles.
Regular replacements are necessary. Every 2–3 months depending on the amount of usage and air quality requirements.
Take the advantages. A longer HVAC life can lower energy bills and clean air.
Proper air filter installation is a must for your home and health. An air filter that is installed properly assists your HVAC system in running efficiently and this way the air will be clean.
In case the filter is not installed properly, air can pass around it and take dirt into your unit. The result can be that your HVAC unit has to work harder, consume more energy and possibly break down sooner. Additionally it may lead to poor air quality in your home.
Installing an air filter properly results in the following:
Saves you money
Lowers your utility bills by using less energy
Lessens frequent repairs
Extends the HVAC equipment lifespan
Installing the right air filter is one of the simplest ways to boost your home’s air quality. Filterbuy filters are designed to fit custom or less common HVAC setups. Thus, accurate installation guarantees the maximum airflow and filtration efficiency.
Here’s the process:
Switch off your HVAC system before taking out the old filter.
Find the filter slot. It is usually located near the return air duct or blower compartment.
Look at the airflow direction arrow on the filter frame.
Place the new filter with the arrow directed to the HVAC, not the opposite way.
It should fit tightly. Prevention of air escaping in a circular path is a result of having tight seals and can therefore prevent dust formation and acquired allergens from the appliance.
Every two or three months, it is recommended to replace filter depending on how often the HVAC is used, presence of pets and allergy situation.

Indoor air is 2 to 5 times more polluted than outdoor air according to the Environmental Protection Agency.

This air filter is intended for custom HVAC units that have non-standard sizes. Its operation involves the capture of dust, pollen, and other particles, thereby ensuring a clean air supply and protection for your HVAC system from dirt build-up.
Check the label of your current filter or take its dimensions: length, width, and depth. The size must be absolutely perfect. If not, there will be air leakage which will result in less efficiency of the system.
Replace it every one to three months. But if you have pets, suffer from allergies, or the air quality inside your house is not good, then replace it more often.
MERV 8 - Okay for basic control of dust
MERV 11 - Suitable for households with pets or allergies
MERV 13 - The best choice for trapping smoke, bacteria, and fine particles
It is not a common size filter. It is for unique or custom HVAC units. Maintaining a good seal and airflow is possible only when using the exact size filter.
