There are many different kinds of filtration systems designed for homes, but the simplest thing to do is focus on the heat and air system you already have. These systems often will have easy access to the air filters in place.
The first thing to remember is to change your filter regularly. While the CDC recommends every three months, our experience is that is not often enough. Filters tend to get dirty much faster than that depending on many different factors of course. And all you really need to do is visually inspect your filters and as they are accumulating dirt then you will know it’s time to replace them.
Can you wait longer to replace them? Well, yes, but what is more important? Your health and the health of your loved ones? Or a few more dollars per year? The amount of additional money you might save by using the filters longer you will probably lose in one co-pay visit to your doctor because you got sick.
What quality of filter should you use? The CDC recommends “pleated filters” as they are more efficient. And while we agree with that, we don’t think it goes far enough. You want a filter that is created to trap more particles in the air especially virus particles. You do this by selecting a filter with a higher MERV rating and we recommend the MERV 13. If you are wondering what does MERV stand for then visit our article to learn more.
Another CDC suggestion which is not a bad idea is to set your thermostat to the fan “on” position instead of “auto.” They suggest doing this when you have visitors. What it does is causes the air system to keep circulating the air and therefore filter it without shutting off. This will increase the ventilation for homes without much additional expense. This suggestion also fits well in the next category.
