How To Improve Your HVAC System’s Efficiency By Installing The Right Air Filter?

Must Read

If you want to improve the efficiency of your home’s heating and cooling system, it’s important to install the right air filter 14x18x1. Not only will this help to reduce energy costs, but it can also improve your indoor air quality. In this article, we’ll discuss the different types of air filters and explain how they can help improve your HVAC system’s efficiency. 

When it comes to air filters, there are three main types: mechanical, electronic, and chemical. Mechanical filters are the oldest type and work by trapping dust, pollen, and other airborne particles. Electronic filters use advanced sensors to detect airborne particles and then use a control mechanism to adjust the airflow in order to reduce or eliminate them. Chemical filters use chemicals to remove particulate matter from the airstream.

Of the three types of air filters, mechanical filters are the least efficient. This is due to the fact that they have a higher MERV rating (Minimum Effective Recognized Volume). MERV ratings represent how well a filter traps smaller particles. The higher the MERV rating, the more effective the filter is at reducing particles. Electronic and chemical filters have a lower MERV rating, but they are more effective at reducing particles because they can trap larger particles.

What is an Air Filter?

An air filter is a device that helps to clean the air that enters a home or office building. Air filters are also used to control noise and heat in an HVAC system. 

Most air filters are made from a variety of materials, including cloth, paper, and synthetic materials. Air filters are generally available in matted or pleated versions. 

How do air filters work?

Air filters are designed to trap dust, pollen, and other small particles that may be harmful to the health of people and animals. Air filters may also help to improve the airflow in an HVAC system.

Types of Air Filters

There are several types of air filters, each with its own specific pros and cons. 

Residential air filters come in a few varieties, including pleated, synthetic media, foam-type, and electrostatic types. Each has its own advantages and disadvantages. 

Pleated filters are good at capturing large particles but can be less effective at trapping smaller organisms such as dust mites. Synthetic media filters are good at capturing both small and large particles but may require more cleaning than pleated filters. Foam-type filters are good for catching large particles but can be less effective at trapping smaller organisms. 

Electrostatic filters work by attracting and holding dirt, dust mite feces, and other allergens in the airstreams for disposal. They are usually the most expensive type of filter but generally have the longest life span and are best for Dustmite allergies or asthma sufferers. Chlorine Bleach Filters: Chlorine bleach (bleach based EPA registered pesticide) is often used to treat air contaminants before installing an air filter because it is very effective at destroying airborne pathogens (bacteria, mold spores) without causing any harm to people or animals that breathe it in.

How Does an Air Filter Improve My HVAC System’s Efficiency?

An air filter also called an air purifier or HVAC system cleaner is a device that helps improve the efficiency of your HVAC system. An air filter absorbs polluting particles and gases from the indoor environment and converts them into less harmful forms. This helps to reduce the number of pollutants in your home’s atmosphere, which in turn allows your HVAC system to work more efficiently and save you money on energy bills.

So how does an air filter improve my HVAC system’s efficiency? There are a few ways: 

1. Air filters trap dirt, dust, pollen, tobacco smoke, and other pollutants before they can reach your conditioned space. This can help to significantly reduce the number of asthma attacks, as well as allergies and respiratory problems in general. 

2. Air filters can also improve the performance of your heating and cooling systems by removing small particles that can cause scratches on heat registers or fan blades, leading to inefficient operation. In extreme cases, this can lead to complete system failure! 

3. Particles caught by an air filter can also clog up your furnace blower motor, reducing its ability to pull fresh air into your home. Over time this will eventually cause your furnace to stop working altogether.

Which Air Filter Should I Purchase?

There are many types of air filters available on the market today, and it can be difficult to determine which one is right for your specific home or office. The three most important factors to consider when purchasing an air filter are size, type, and certification. 

The size of the filter will depend on the size of your HVAC system. If your system has a reverse osmosis unit, you will need a larger filter than if your unit uses furnace filters. Filters with higher standards must be capable of capturing smaller particles as well as larger ones. 

Type is also important to consider when purchasing an air filter. Filters that are certified by the EPA or CARB should be chosen over other types of filters if possible. These filters have been tested and proven to be effective at reducing pollutants in the air. 

Lastly, you need to decide what kind of filtration you require. Pre-filters capture small particles before they reach the filter media, while post-filters catch larger particles after they have passed through the media.

Installation Guide for Air Filters

An air filter is essential for improving the efficiency of your HVAC system. This installation guide will help you choose the right size and type of air filter, as well as install it. 

This installation guide is for residential air filters. For commercial or industrial filters, please see our separate installation guides.

Before you begin: Check your furnace’s label to find out what kind of filter it requires. AFits may have specific requirements such as MERV ratings (see below), so be sure to consult your furnace’s manufacturer before installing an air filter. If you don’t know what type of filter your furnace needs, call a professional!

Some common types of filters are listed below. Consult a certified technician if you are unsure which one is right for your home. All types of filters should be replaced at least every six months, even if they seem to be working fine – fresh airflow will help reduce indoor pollutants and fouling build-up over time. Once you’ve determined the correct type of filter, make sure you have:  

-The correct size for your furnace; most furnaces require an inch-by-inch fit 

-Enough space on the internal parts of the unit to accommodate the new filter 

-A vacuum cleaner with a hose attachment – this will help remove any dirt or debris from inside the unit prior to installing the filter.

Installation guidelines:

1) Turn off power to the house at both main switches ( if applicable)

2) If you have a central air conditioning unit, turn off the fan running to it

3) Open any windows in your house to allow fresh air in

4) Make sure that the furnace is properly assembled before beginning. Refer to your furnace’s instruction manual if needed

5) Remove all the insulation from around the outside of the furnace filter should be placed on an even and stable surface, such as a concrete slab or some type of leveled tray. The filter can weigh up to 75 pounds! Once you have chosen the filter and location, use a level to make sure it is perfectly horizontal and plumb. If necessary, place blocks at both ends of the filter in order to prevent it from tipping over.

6) Hold the vacuum cleaner hose against one end of the filter and turn on the vacuum cleaner. When the air inside starts flowing rapidly through the filter, release the vacuum cleaner attachment. DO NOT PUSH OR HOLD THE HOSE TIGHT – GRAVITY WILL MAKE THE FILTER CRUSH

7) Repeat steps 5-6 for the other end of the filter

8) Replace insulation around furnace intake ducts and close any openings around the ducts with caulking or wire meshOnce the installation is complete, test the filter by running the furnace for 30 seconds. Be sure to close all windows and doors before starting the test.


Air filters are crucial for improving the efficiency of your heating, ventilation, and air conditioning system. By choosing the right type of air filter, you can help to remove pollutants and allergens from the indoor air, which will in turn improve your home’s overall comfort level. Not only will this have an impact on your energy consumption, but it could also save you money in the long run. Considering an HVAC system’s air filter?
