Air Filters / Air Purification Systems
There are 3 main kinds of air filters: pleated, fiberglass, and media filters. Let’s talk about each one and learn about their benefits.
- Pleated Air Filters: Typically, a MERV 6 or higher (MERV = quality of filter) has better air flow allowance for your furnace or a/c unit.
- Fiberglass Filters: These keep the “big” stuff away and out of your furnace. However, the way they were made doesn’t do much for the tiny things. They also have a low MERV rating, which means they do a decent job but are not as good as pleated filters.
- Media Filters: These filters are pleated but are 4” thick or more. These have those lines you see on your filters but they are thicker than the average pleated 1” filter. So, they do an even better job of keeping animal hair or dust bunnies away.
PLEASE BEWARE: A HIGHLY RESTRICTED FILTER IS NOT A GOOD THING! This is why we are always told to check and / or change our air filters!
We also have something called an Electronic Air Cleaner. When the air passes through and collects all the particles in the air, it sends them through an electric field that is about 10,000 volts. They get a positive charge, and once they get to the filter that acts like a grounding mechanism they cling to it and won’t go any further.
Then there is an Electronic Media Filter which is pretty much the same as the air cleaner but the Media filter has 4” grounding strips attached to the filter. Which is a larger area to work with to make sure those particles are being grounded and kept out of the furnace or AC.
Whole-home purification consists of 3 main components:
- A MERV 16 media filter which collects all those bad air particles.
- A UV light system (non-ozone producing) which takes care of the VOC (bad) gases that may be in your home air.
- A charcoal-style filter that eliminates bad smells in the home.
You can also take the UV light system and connect it externally to your furnace system. This will kill any mold or dust, and it takes care of those pesky allergens that some of us have to deal with as far as allergies go.
Now that you are aware of the benefits of these different types of filter and air purification systems, let’s move on to humidifiers and dehumidifiers.
There are a few different types of humidifiers that can be used in the home, as described below:
- Bypass humidifier: It mounts onto the furnace and a duct runs from the humidifier, attaching to the return. When the system calls for humidity, the humidifier will turn on and operate. This system is best used with a single-stage furnace because, with the two-stage or modulating furnaces, the blower motor does not have enough power to blow the heat and water through the humidifier pad equally. With the single-stage furnace, the motor constantly runs equally, allowing for water at the top of the humidifier tray to run through the pad and blow out of it equally in the ducts.
- Power humidifier: Thismounts on the furnace and has the same pad system as the bypass. This humidifier has a built-in fan, which allows the unit to work with all types of furnaces. The tray is on top of the humidifier, allowing water to be distributed through the pad and into the air when the fan kicks on. This unit needs to be in the heating mode for it to operate properly, and the fan needs to be running.
- Steam humidifier: This can mount anywhere in the home where the unit can be connected to the ductwork. It can even operate in homes that do not have duct work. This unit can just go onto the fan coil of the furnace. This unit, by far, creates the most humidity in the home.
Dehumidifiers (Remove Humidity)
There are a couple different types of dehumidifiers that can be used in the homes. Dehumidifiers remove humidity and are considered to be self-contained air purification systems. All dehumidifiers are either low-ambient control or non-low ambient control.
- Freestanding dehumidifiers: can go anywhere on the floor, and do not have to be ducted into anything to operate.
- Ducted dehumidifiers: work for the whole home, but need to be connected to the furnace system with the special control. Fan and dehumidifier turn on with the click of a button.
