Furnace filters are one of the most important parts of your furnace. If you have an older unit in your house, you should replace the filters regularly (or hire a professional to do it). To ensure proper airflow and keep your house comfortable in the winter, you should change it every three months. But if you’ve never owned a home with a furnace before, how do you know where to start?

To save you the trouble, here are some straightforward answers to the 3 most common questions about furnace filters.

What to Look For in The Best Furnace Filters For Allergies?

Furnace Filter

It can be difficult to find the right furnace filters for allergies. Some might want to focus on air quality while others prioritize allergy protection. And, it’s easy to get lost in each model’s different features. That’s why we’ve outlined the main factors that affect performance, so you can make the best buying decision for your home.

MERV Rating

When you’re looking for furnace filters, you might notice the abbreviation MERV rating. This rating is important when it comes time to choose a filter. It shows how efficient the filter will be at trapping dust and other impurities. MERV is an acronym for Minimum Efficiency Reporting Value. It denotes a filter’s efficiency in trapping dust particles or other particles that may find their way into your home.

The higher the value of the MERV rating, the more dust and allergens it can filter out. For your home, you’ll want to pick a filter with an efficiency rating between 7 and 13.


Fitting a filter into a furnace can be tricky because these machines vary in size and shape. To ensure you don’t buy the wrong one, make sure to read your machine’s specifications beforehand. When buying an air conditioner filter, always go for one that’s made for your model. They’ll fit perfectly, without any gaps or crevices.


The thickness of a furnace filter tends to denote its effectiveness. Thicker filters tend to provide better filtration than thinner ones, so you’ll have less dust in your home.

Do Furnace Filters Actually Help With Allergies?

The debate over whether or not furnace filters help with allergies has been going on for years. Many people believe that they help, but others believe they’re a waste of money.

The truth is, furnace filters do help with allergies. They trap dust and other allergens that might make you sneeze, get a runny nose, and make your eyes water. But if you have a lot of dust and pollen in your home, you should clean your home and furnace filters regularly.

Furnace filters get dirty with dust and allergens over time, so you should always have a fresh one on hand. You may need to replace cheap and disposable filters every month, while more expensive ones can last for several months.

What Is The Best MERV Rating For Allergies?

The MERV rating is a number that indicates the efficiency of air filters. The MERV scale goes from 1 to 16. Higher numbers indicate a more efficient filter that are better able to trap dust and catch particles that may not be visible to the naked eye. This is important for people with allergies because they’re bothered by microscopic particles in the air. These particles can penetrate regular filters and cause serious reactions.

If you suffer from allergies, look for a MERV rating between 11 and 13.

To increase the efficiency of your filter, you may want to get a pleated version. They’re better than non-pleated ones because they have more surface area. So, air can pass through them more easily. As a result, they are less constrictive to the flow of air in your system and are better at filtering out particles.


Furnace Filter

Furnace filters are an easy way to keep your HVAC system and the air you and your family breathe clean. If you have a sensitivity to certain allergens in the air, your doctor will likely tell you to check if there is adequate filtration in your home. When purchasing a furnace filter, it’s important to look at the MERV rating to ensure proper filtration.

With a MERV rating of 12, the Filtrete AC Furnace Air Filter traps dust and pollen particles in all seasons. It has excellent filtration at a low price, making it an accessible choice for everyone.
