Reusable Furnace Filters: Do They Actually Work?

installing a furnace filter

The furnace’s air filter is designed to trap dust in the air. The filter needs to be cleaned and replaced regularly to work effectively.

In this post, our specialists in HVAC in Ajax are discussing what you need to know about reusable furnace filters and whether or not they actually work:

What Is a Reusable Furnace Filter?

A reusable furnace filter is a type of furnace filter that can be reused after it has been used to filter out particulates from the air. Reusable furnace filters are typically made of metal or synthetic materials, and they can be washed and reused multiple times.

Reusable furnace filters are an alternative to disposable furnace filters, which are designed to be used only once and then thrown away. Disposable furnace filters are made of paper or fiberglass and can only be used for a limited time before they have to be replaced.

Is It Necessary to Use High-Quality Furnace Filters?

There are various furnace filters on the market, and it can be tempting to save a few dollars by opting for a cheaper option. However, it’s important to remember that a furnace is a significant investment, and using a high-quality furnace filter is among the best ways to protect it.

What Is the Difference between Disposable and Reusable Filters?

When it comes to filters, there are basically two main types: disposable and reusable. Disposable filters are designed to be used once and then thrown away, while reusable filters can be used several times before needing replacement.

 Disposable filters are often made of paper or fiber, while reusable filters are usually made of metal or plastic.

Pros and Cons of Reusable Furnace Filters

Are reusable furnace filters really the best option for your home? Here’s a look at the pros and cons of using a reusable furnace filter:


1. Cost Savings

One of the biggest advantages of using a reusable furnace filter is the cost savings. These filters typically cost more upfront than disposable filters, but you won’t have to keep buying new ones every few months. In the long run, reusable furnace filters can save you a significant amount of money.

2. Environmentally Friendly

Another benefit of reusable furnace filters is that they’re more environmentally friendly than disposable filters. Once you’ve used a disposable filter a few times, it ends up in the landfill where it will sit for years. On the other hand, you can wash and reuse a reusable furnace filter, which cuts down on waste.

3. Better Air Quality

Some studies have shown that reusable furnace filters can actually improve the quality of the air in your home. That’s because these filters are designed to trap smaller particles than disposable filters. If you’re looking for better air quality, a reusable furnace filter is a good option.


1. Requires Regular Cleaning

One of the downsides of using a reusable furnace filter is that it requires regular cleaning. You’ll need to remove your filter from the furnace and wash it at least once every three months. If you don’t keep up with the cleaning, the filter won’t work as well and your air quality will suffer.

2. Can Be Difficult to Clean

Cleaning a reusable furnace filter can be a bit of a hassle, especially if it’s very dirty. You’ll need to use a mild detergent and make sure you rinse the filter thoroughly. If you don’t clean the filter properly, it could end up damaging your furnace.

How Often Should You Change Your Reusable Filter?

The answer to this question depends on a few factors, including the type of filter you have and the amount of use it gets. In general, however, most reusable filters should be changed every one to three months.

The type of filter you have will play a role in how often it needs to be changed. Also, the amount of use your air purifier gets will also affect how often you need to change the filter. If you use it often, you may need to change it more often than if you only use it occasionally.


Reusable filters are a good option for many reasons. They are cost-effective, eco-friendly, and easy to use. With so many benefits, it’s no wonder that more and more people are making the switch to reusable filters.

Climate experts came in for HVAC/boiler maintenance when we moved into our new house. They ended up finding a problem that went undiagnosed by our home inspection that could have been very dangerous. They then ended up installing a new boiler for us super quickly. It was obviously a sudden expense but Climate experts made the whole thing feel a lot better due to their professional and concern for our safety. The new boiler not only works, but is...dare I say...beautiful! The copper piping work that they did is a sight to behold. Who knew that we would be so excited to show our family/friends our cool new boiler. We absolutely recommend these folks—they are reliable, professional, and make even the typically boring part of the house feel nice and pretty. You are in good hands with them!
