Air filters are an essential component of every household and play a crucial role in ensuring clean and healthy air. With the increasing awareness of indoor air pollution, choosing the right air filter has become a critical task for every consumer. This guide will help you understand the different types of air filters, the factors to consider while buying an air filter, and the best practices to maintain it.
Types of Air Filters
There are several types of air filters available in the market, and each type has its own unique features and benefits.
MERV Rating
The Minimum Efficiency Reporting Value (MERV) rating is a standard used to measure the effectiveness of an air filter. The higher the MERV rating, the more efficient the air filter is in trapping smaller particles. Please note that having an air filter too dense may restrict the airflow in your system.
Fiberglass Filters
Fiberglass filters are the most basic type of air filters and are primarily used for their low cost. They are effective in trapping larger particles but not so much for smaller particles. They are usually the cheapest filters you can find. Not recommended by Expert Duct Cleaning.
Pleated Filters
Pleated filters are an improvement over fiberglass filters and are more efficient in trapping smaller particles. They have a larger surface area, which enables them to trap more particles. These are the most common filters used in HVAC units today. Pleated filter is great to use if you don’t have allergies of special conditions that are affected by some smaller particles.
HEPA Filters
High-Efficiency Particulate Air (HEPA) filters are the most efficient type of air filters available. They are capable of trapping even the smallest particles and are ideal for people with allergies or respiratory problems. These are the most expensive filters you can buy and they may restrict the airflow in your ductwork.

MERV Rating
The MERV rating is an important factor to consider while buying an air filter. If you have allergies or respiratory problems, you should choose an air filter with a higher MERV rating.
Cost
Air filters come in a range of prices, and the cost is an important factor to consider while buying one. While more expensive air filters may be more efficient, you should choose one that fits your budget and meets your needs. Just stay away from the very cheap ones where you can stick your finger through through the filter.
Maintenance
The maintenance required for an air filter is an important factor to consider. Some air filters may require frequent replacement, which can be time-consuming and expensive. Some filter are washable.
