Choosing The Best Square Air Filter

Best Square Air Filter

Square air filters offer many benefits, including a longer lifespan and more efficient filtration.

One of the main benefits of using a square air filter is that they have a longer lifespan than other air filters. This is because their square shape allows less air to bypass the filter, so they will need to be replaced less often.

Square air filters also tend to be more efficient at filtering out particles, making them an ideal choice for those with allergies or asthma. However, picking the best type of square air filter for your home can sometimes be confusing with the many different models and brands.

Here are some suggestions to help you make a better decision when selecting the best type of filter for your home or business.

Types of square air filters

Square air filters are the most commonly used filtration systems for residential and commercial applications. They are designed to filter the air before entering your home or business, which can help reduce allergens, odours, and dust.

Square air filters come in various sizes, which includes furnace sized 20x20x1 air filter, mid-sized 14x14x1 filter and so on. 

You’ll want to choose one that fits your needs. If you’re looking for a replacement for your existing square air filter, then choosing one that’s the same size is easy.

However, if you’re installing a new square air filter, then it’s essential to choose one that will fit properly in your HVAC system and provide adequate airflow throughout your home or office space.

There are two main types of square air filters: permanent and disposable. Each has advantages and disadvantages, but you can use them both in residential and commercial settings.

Permanent

Permanent square air filters are heavy-duty materials you can wash or reuse multiple times. They typically last for 6 to 12 months before needing to be replaced, making them a more economical choice in the long run. 

However, they require more maintenance than disposable filters and must be cleaned regularly to prevent the buildup of dirt and dust.

Disposable

Disposable square air filters are from paper or fibreglass and are designed to be used only once. They’re a good option for people who don’t want to worry about cleaning their filters, but they’re not as cost-effective in the long run. 

You have to replace these filters more often, usually every 1 to 3 months.

Sizes of square air filters

There are many different sizes of square air filters. The two most common 1-inch square air filters are:

  • 20x20x1 air filter
  • 12x12x1 air filter
  • 14x14x1 air filter

These are the sizes you will see when visiting a home supply store. These numbers relate to the standard size of the return air vents in your home or business.

Knowing the two types of square air filters and the most common sizes available in the market, you are now better equipped to select the correct square air filter for your home and family.

Final Thoughts

So there you have it with all of that information. Choosing the right square air filter for your home or business should be easy. 

First, you need to look at the size you need and not just the square footage one will cover.

Second, you also want to make sure you choose the right type and try to find more information about them if necessary. Choosing the right square air filter will keep your HVAC system operating at peak performance. 

Hopefully, this article has helped you understand the importance of square air filters in your home.
