With many more adults working from home and kids schooling from home, keeping a home’s inside air clean is becoming a major priority for most families. But as many consumers are realizing, air purification systems can be complex. Which one is best for your circumstance? What do all the terms mean? How can you make your air safer?
Forced hot air systems contain air filters to capture dust and debris before they enter the furnace that heats the air. Air filters help to keep your furnace safe and in working order. What you may not know is that there are different levels of filters that capture different size particles floating in your air. These particles range from dust and fuzzies to pollen, bacteria, and viruses.
Furnace filters are rated on a MERV scale – which stands for Minimum Efficiency Reporting Value. The scale is ranked from 1-20, determining their effectiveness at catching various sized particles. Many homes generally have a filter rated between 5 and 12. These filters are good for catching mold, dust, and pet dander. Filters with a rating of 13, are considered hospital-grade filters that can capture bacteria. Filters with a MERV rating above 17 can capture viruses and even carbon dust.
It is important to familiarize yourself with the specific needs of your family and purchasing a filter with the appropriate rating. If you need some help in determining how to make a good decision on air-filter selection, keep reading below.
Which furnace filter is right for me?
That depends on many factors you may want to consider:
Air purification systems that work off of ionization work on the principle of putting negative ions into the air. These ions contain a negative charge which in turn, binds itself to debris that passes through your air. When enough of these ions cling to a dust particle, virus, or bacteria, they create a static-like charge that binds them to an air filter.
Ionizers, like the iWave air purifier, are placed inside your forced hot air system to put these ions into the system’s air before it reaches the air filter. These ions bind to particles that are then trapped by your air filter. As mentioned above, a system like the iWave, paired with an air filter, is incredibly effective against dust, pollen, bacteria, and even viruses like SARS-CoV-2. These systems are great for both home and business use, have great lifetimes, and require little upkeep to maintain their working order! You just change your air filter on a regular basis, like normal.
UV light air purifiers work on a different principle, one you’re familiar with if you’ve ever gotten sunburned – they break down particles, bacteria, and viruses that float in your air using UV light. Since UV light degrades what it comes in contact with, particles that pass through a UV light system also break down, just like sunlight when it damages your skin.
Yes – they are enclosed in your forced air system and are completely safe in both home and commercial uses. UV light systems are designed to kill germs, are the UV light is exposed to humans. It should be mentioned that UV light air purification systems require some regular upkeep – replacing the bulbs and keeping them free of dust helps to keep your air cleaner.
If you have forced hot air, you can easily check your air filter MERV rating and update it to what you feel is best. The next step is making a choice based on personal preference – do you want an ionizer or a UV light system. Both do a great job of removing harmful particles from your home’s air.
