The Best Air Vent Filters Reviews In 2021

Having the best air vent filters in your home provides you with an extra line of defense, as this is an essential way of preventing dust and allergens. Dust and allergen particles can enter the ducts and through cracks, and bypass the main furnace filter – which may result in health problems.

Dust can also accumulate in vents when there’s no activity going on, and this ends up further polluting your home or space. Luckily, installing air vent filters is an excellent way of preventing all this from happening as it delivers fresh air to your home. 

If you’re searching for a good air vent, we have several options below that we’ve reviewed to help you out.

What Is a Vent Filter?

A vent filter is simply an object that is used to filter incoming air on a receiver when it ventilates. Vent filters are ideal to use in your home, especially because they help to prevent bad odor, smoke, and other pollutants from entering your home. Therefore, a vent filter helps to offer you cool and fresh air.

 With vent filters, you are guaranteed an extra line of defense against allergens and dust. If you are allergic to dust, using a vent filter can be a great solution to prevent these pollutants from causing you allergic reactions. Additionally, vent filters come with a lot of benefits that we’ll list down below in the pros and cons section.

Do Vent Filters Work?

The simple answer to this question is a resounding yes! Vent filters can work wonders – but only if you buy and install some of the best air vent filters to use in your home. Using a vent filter is one way of adding to your main filter, and it’s also suitable for homes that have their HVAC system off mostly.

Although vent filters don’t entirely eliminate the problem, they are reliable when it comes to reducing airborne allergens like pollen and dander. These particles are pulled into the return vents and then caught in the furnace filter. Simply put, using vent filters is an integrated way of filtering indoor air.

However, there are instances when you need to avoid using vent filters such as in older homes. When you have an older home, it’s not always recommended to install a vent filter because it’s almost like placing a bandage over a broken house.

This is mainly because the vent filters can catch a large percentage of particles, but your heating bills will be impacted due to the leaks in the ducts.

Pros and Cons of Vent Filters

Vent filters also come with their own advantages and disadvantages, similar to most components of an HVAC system. 


  • They protect you against dust and allergens
  • Vent filters are efficient and easy to use
  • They are easy to install
  • Some of the best air vent filters are cheap and affordable
  • Vent filters are made from high-quality materials
  • Vent filters prevent the accumulation of dust in the vents during periods of inactivity
  • Vent filters also prevent further pollution of your home


  • Unfortunately, vent filters slow the passage of air because as particles build upon them, it increases the amount of obstruction.
  • Vent filters can rack up your energy bill since they cause your system to work harder. 
  • Vent filters can potentially overheat components.
  • Vent filters require regular changing, similar to your main filter.

When to Use Vent Filters

Vent filters often make a huge difference in various situations, but they don’t always solve air quality problems. The quality of air entering your home can be jeopardized by plenty of sources, but your furnace filter can do an excellent job of protecting you from airborne particles under normal circumstances. 

If your home HVAC normally remains off mostly throughout the year, that’s when you should consider using vent filters. In such a place, an air vent filter can assist in reducing the accumulation of dust in the vents. Therefore, this ends up reducing the heated dust smell that occurs when you first turn on your furnace after it was off for long.

However, you shouldn’t on vent filters as the main solution for dealing with dust and other pollutants blowing into your home. Unfortunately, vent filters don’t deal with the entire issue, which means you have to implement other things such as an air conditioning system or any other reliable device to assist in tackling this issue.

When Not to Use Vent Filters

As mentioned earlier, you should highly avoid using vent filters in older homes. That’s because the ductwork can easily accumulate holes and cracks over time, and the seals can also break. This issue is most common in an older home where dust gathers quickly in its rooms, but the furnace filter still stays clean. 

When this happens, the vent filters tend to accumulate a lot of particles, thereby leaking in the ducts and resulting in high energy bills. Therefore, a good solution for this issue would be to make sure the ductwork is properly checked and repaired for it to last longer. 

Another reason why it’s not ideal to use vent filters in older homes is due to the furnace. Furnaces require air to prevent them from overheating or becoming inactive. Therefore, adding filters in an old house may reduce the airflow and negatively affect the furnace.

Do Vent Filters Block Air Flow?

Yes, vent filters tend to block airflow. In fact, this is one of the biggest drawdowns associated with vent filters. The reason why vent filters block the airflow is that they slow the passage of air as particles build upon them. This ends up increasing the amount of obstruction and causes your system to work harder than it should.

How to Install Return Air Vent Filters

Here is a step-by-step guide on how to install return air vent filters:

  1. The first step is to clean the vent. You can do this by turning off the HVAC unit and opening the vent grille. You also need to decide whether you want to place the duct inside or outside the grille. 
  2. Cut it into the perfect shape. Most of the return vent filter brands have rolls that you need to cut to conform to your vent’s shape. Before you cut, first you need to apply the tape to avoid overlapping the fins on the grille. Use scissors to cut and get the best shape.
  3. The final step involves pressing the filter onto the tape that you secured to the grille, and then hold for several seconds.
