What is the Best Furnace Filter?

If you are like most people in Calgary, you probably do not give much thought to your furnace as long as it is keeping you warm. But to keep it working at its optimum best, you have to make sure that the filter is cleaned consistently, or replaced with a better model. While the latter might sound easy, there is a lot to take in when it comes to getting the best filter for your furnace.  

Checking The Filter Ratings Before Furnace Installation

Furnace air filters are given a MERV (Minimum Efficiency Reporting Value) rating to measure its efficiency and effectiveness in airflow and cleaning particles. The system rates air filters from 1 (the lowest and less efficient) and 16 (the highest and most efficient). For households, a range between 8 to 11 is sufficient. You can also speak to a professional about the MERV rating when you get a furnace installation service in your home.

There Are Numerous Types Of Filters For Furnace Installation

There are three distinct types of filters that can work for your furnace. All vary in price and efficient. These include:

  • Disposable Pleated Filters. These are the most common option for homeowners as they come in a range of standard sizes, and are not overly expensive. They are made out of paper and polyester, and while durable, need to be changed every three months or so.
  • Disposable Fibreglass Filters. These are the cheapest options on the market, due to their fragile nature and low MERV rating. They need to be checked or replaced regularly to ensure efficiency.
  • Permanent Reusable Filters. Perhaps the best option on the market. Made from solid aluminium, they are more durable than other options available. They are the most expensive to purchase but last an average of five years. You will need regular furnace cleaning to maintain efficiency (around every 90 days).

Furnace Replacement In Calgary Is Available

Once you know what type of filter you want, you should be able to get it replaced immediately. A professional should be able to help you with the replacement if you cannot do it yourself. If you find that your furnace is still not functioning correctly, you might need to get it replaced. Thankfully, there are plenty of professionals that offer furnace replacement in Calgary.
