Why You Should be Using an Antimicrobial Filter in Your Portable Air Conditioner

Portable air conditioners are used in a variety of situations and are designed to make staying cool easy and effortless. Students living in small apartment buildings use portable models so that they can take the units with them as they move from place to place. Established couples and families with larger homes use the devices to spot cool those areas of their home that can be hard to keep cool otherwise. Many buildings don’t have central air, and the portable units offer both convenience and comfort for people at home and at work.

Regardless of the reason, more and more people are turning to portable air conditioners to keep themselves cool. Many people are also turning to the use of Antimicrobial Filters in their cooling units, as well.

Let’s delve into what these filters are and why they might be beneficial to use in conjunction with a portable air conditioner.

What is an Antimicrobial Filter?

Antimicrobial Filter

Filters have long been used in air conditioner systems. Portable air conditioner systems are no different. An antimicrobial filter, not surprisingly, is one of the most popular filtration accessories for your portable air conditioner.

Much like any air conditioner filter, an antimicrobial filter is designed to remove particulates and harmful irritants from the air, cleaning it before it is recirculated back into the room. This also boosts the overall efficiency of your cooling system.

How Do Antimicrobial Filters Work?

To better understand how an antimicrobial filter accomplishes its goals, it is important to realize how it works. Any antimicrobial device is a contraption designed to trap particulates and kill microorganisms. The filters do this by using positively charged elements that attract negatively charged particles and by straining the particles through microscopic crevices and fibers, effectively trapping the airborne pollutants.

Also, much like any other air conditioner filtration system, the filters are able to perform this for up to 3 months, at which point they should be replaced.

Why are People Using Antimicrobial Filters?

It’s hard to know if you should use an antimicrobial filter with your portable air conditioner until the potential benefits are fully realized. Here are the reasons we think they are an essential accompaniment to your cooling system:

1. Breathe Cleaner, Healthier Air

The biggest and most obvious benefit to using an antimicrobial filter is its potential health benefits. These filters work to remove a number of airborne contaminants, including but not limited to dust, lint, smoke, pollen, and mold spores.

Your portable air conditioner is continuously pulling in and pushing out air. If dust or other irritants are in the air, it will be continuously circulated around your area and breathed in by you and your loved ones. Despite the obvious health concerns of breathing in polluted air, this is especially alarming if you have allergies, asthma, or other respiratory concerns. Antimicrobial filters ensure that your air becomes both cool and clean. You will be more comfortable and will be able to breathe easier.

2. Improve the Efficiency of Your Portable Air Conditioner & Save Money

In addition to the health benefits, antimicrobial filters help boost the efficiency and lengthen the lifespan of your portable air conditioner. As we now know, as air moves through the device it carries dirt, dust, and other particles with it. Without a filtration system, these particles are either circulated back into the room or they become trapped in the air conditioning unit.

Over time, these particles will build up within the unit causing a strain on the fan, inner components, and the unit’s ability to circulate air. When you add a filter, however, the airborne pollutants are trapped in the device rather than the inner workings of the unit. This allows the air conditioner to run more efficiently and limits the amount of wear and tear that the unit experiences. Improved efficiency equates to less energy resources used which equates to money back in your pocket.

Although your portable air conditioner will work just fine without an antimicrobial filter, it will work better, longer, and benefit your health with one. Like any air conditioning system, filtration is an important part of efficiency, health, and functionality. If you are already using a portable air conditioner or you’re considering using one, why not add bring extra benefits to your home and family? Your unit, wallet, and lungs will thank you.
