Best Air Conditioner And Furnace Filters For Allergies 2019

Dust, pollen, dander and dust mites may gather in places that escape regular cleaning, such as the HVAC system in your home. If you’re suffering from allergy, you’ll want to consider using air conditioners and furnace filters that are designed to block allergens from passing through.

How Does Air Conditioner/Furnace Filters Work?

Furnaces and air-conditioning systems are two of the most important systems of any buildings. It’s keeping the filters clean for the system’s efficiency and also to maintain the cleanliness of the air in your home.

The function of the air conditioner and furnace filtration system is to shield the blower fan from dust and dirt particles, hair and other pollutants present in the environment. With this, the filtration system also helps to keep your home clean by stopping the recirculation of the dirty and dusty air.

By taking all the dust in the duct, the filters increase the Indoor Air Quality (IAQ) of your home or office, thus cleaning the air around you and maintaining your breathing health.


Is Air Conditioner and Furnace Filtering The Same?

Air conditioning and furnace filters are the same if your place is centrally heated with a furnace or has a central air conditioning system.

Moreover, if you have installed separate heating and cooling units (furnace, AC/ HVAC) which share the same air handling unit to regulate/ circulate the air, then both filters will be same too. Because both air filters are positioned on the same spot of the air handling unit so both heating and cooling devices use the same filtering system.

Ventilation and circulation of air will occur with the help of the air handling system, whether you’re are heating your place with the furnace or cooling your place in the hot summers with the air conditioner.


What Are Air Conditioner/Furnace Filters Made Of?

There are various sorts of AC and furnace filters available in the market which differs on the basis of their material and quality grading. Generally, filters are made with fiberglass, cotton sheets, and polyester.

The filters are graded on MERV ( Minimum Efficiency Reporting Value) scale which grades the filters from 1 to 20, 20 being the highest quality filter. It is advisable to use an appropriate filter for specific furnaces in order to get efficient filtration without damaging the machine.

The fiberglass filters have the lowest MERV rating that ranges from 2 to 4. These filters are an inch thick and safeguard your machine from dust particles. These are very cheap and are installed in most of the furnaces.

Then comes the pleated fabric filters which are disposable. They are made of polyester or cotton sheets. These cotton paper sheets are self-chargeable to ease the removal of dust and other smaller particles. These filters are rated from 6 to 13 on the MERV grading.

Washable filters are made with aluminum mesh and are rated around 8 on the MERV grading system.  HEPA filters are the highest rated filters with the 17 to 20 MERV grading.


Why Getting the Right Air Conditioner/Furnace Filter Helps in Managing Allergies?

While the AC and furnace filtration system are vital to keeping the equipment perfectly functioning, these filters also cleanse the air around you and protect you from airborne allergens. To get the best results, it is highly recommended to install high-quality filters in synchronization with your equipment to attain perfect and efficient functioning of the furnace/ AC.

The quality of the filters is checked by the MERV ratings.  The higher the MERV rating, the greater the quality of the filter will be. Filters with MERV rating from 1 to 4 have dust filtration capacity of less than 20%. These filters protect the air from pollen, sands, dust, textile fibers, carpet fibers, spray paint dust, and things alike.

Filters with 5 to 8 rating on the MERV scale have a dust restriction capacity from 20% to 35% and can restrict the entrance of mold spores, cement dust, hair spray, pudding mix, and fabric protector. These filters are mostly used at industrial workplaces.

Filters with 9 to 12 rating on the MERV scale have a dust restriction capacity of 40 to 75%. These filters protect the air from welding fumes, lead dust, auto emission, and milled flour. Filters with higher ratings on the MERV scale are perfect to guard the machine and air from all types of bacteria, tobacco smoke, and other allergens.

Highly efficient filters have a great capacity to protect the air from airborne allergens. These filters masterfully capture the dust particles containing allergens and hinder the recirculation of the dirty air. Thus, these filters protect you from allergic reactions.
