Top 6 Indoor Air Filters For Your Home

Posted on: October 8, 2014

The air quality of your home can be greatly affected by the type of filtration system that you have installed. Filters are meant to keep you indoor system and coil clean, some go a step above that and clean the contaminants in the air increasing the level of air quality. This is big for many homeowners, especially if a family member suffers from allergies, asthma, or worse, a medical condition requiring a clean environment. With today’s tight home construction, many new homes suffer from very unhealthy indoor air caused by paints, carpets or other materials in the home. With the dizzying array of filter choices at the local hardware store, misleading infomercials, etc. how does a homeowner know what they need? Moore Mechanical is here to help you find the best solution and select the best filtration option for your home giving you’re the greatest level of indoor air quality.


MERV Ratings
Before we get into specific types of filters, let’s talk about MERV Ratings. MERV stands for “Minimal Efficiency Reporting Value.” MERV is used to describe the effectiveness or efficiency of air filters. This rating helps determine the best filter for specific things like improving health, reducing energy costs and/or increasing the efficiency of the heating and cooling system.

Filter Options
As stated above, there is a dizzying array of filter options to choose from.  To start, here are the filtration options that we recommend…

Disposable Filters:
Pleated disposable filters are made of tightly woven fiberglass and are usually 1”, 2” or 4” thick. The pleats give the filters more surface area so that they do not have to be replaced as frequently. These filters are a bit more efficient (MERV 8 to MERV 13) than regular non-pleated fiberglass filters but not as efficient as electrostatic, electronic or HEPA filters.


Electrostatic filters consist of plastic material on one side and a large carbon filter on the other side. When dirt goes through the layers of the filter, an electrostatic charge occurs and traps the dirt. These filters are more durable than a standard filter and are washed rather than replaced. Washing the filters monthly with water is recommended. Electrostatic filters can be cut to exact size requirements or can be purchased in standard sizes.



Electronic filters use a process called electrostatic attraction to trap charged particles as small as 1.0 microns, including smoke and dust particles. They draw air through an ionization section where particles obtain an electrical charge. The charged particles then accumulate on a series of flat plates called a collector that is oppositely charged. Ion generators, or ionizers, disperse charged ions into the air, similar to the electronic air cleaners but without a collector. These ions attach to airborne particles, giving them a charge so that they attach to nearby surfaces such as walls or furniture, or attach to one another and settle faster. The large cell plates must be removed and cleaned regularly


HEPA Filters:
HEPA filters like the IQ Air Perfect 16 clean 100% of the air in your home and can effectively filter the air down to 0.003 microns. There is no ozone generation, ionization, ultraviolet radiation, chemicals or other byproducts seen in other filtration devises. Air is drawn through your home’s return grill and then filtered through pleated micro-fiber filtration panels inside of the filtration devise that is installed at the existing furnace location. These filters can give up to 50 times more filtration than ordinary filtration systems. This traps harmful micro-particles each time the system heats or cools your home up to 125 times per day. Not only that but they are energy efficient!


Air Purifiers:
Air purifiers like the Carrier Infinity air purifier are a installed at your existing furnace system. They don’t just filter the air in your home, they capture and kill airborne pathogens such as bacteria, viruses and mold. This whole house air cleaner re-purifies indoor air as many as 8 times an hour. The cartridge pulls electronically charged contaminants through an electrical field toward itself and keeps them there. The contaminants are then killed off as electrical currents and ions flow through the cartridge. With a MERV rating of 15 these filters are not only effective but incredibly high efficient.


UV (Ultra Violet) Lights:
UV lights are installed in the ductwork of your central air system and are designed to help reduce airborne odors, toxic chemical vapors, germs and mold in your home. Activated carbon cells inside APCO are kept clean by the photocatalytic effect of the UV light. This means the system is virtually maintenance-free.
