When Do You Need to Buy an Air Filter?



If you live in an industrial area where the air is particularly polluted, then you’re probably going to need a good air filter. People today are becoming increasingly more aware of the importance of air filters, especially due to Coronavirus concerns. Although the virus cannot be transmitted by air, you’ll still want the air in your house to be the healthiest and highest quality. Air filters and air purifiers are also the favorite products for people with seasonal allergies, as they can effectively filter out pollen and allergens out of the air. So, if you don’t have any device that filters the air in your house, here’s why, and when, you should get one.

When Your HVAC Unit Wastes Energy

If you notice that your energy bills are becoming increasingly high while your HVAC unit’s efficiency significantly drops, this might be because your air filter is clogged and needs changing. The air filter manufacturers at explain that the dust and debris in clogged air filters within your HVAC unit will inhibit the heating and cooling mechanism from working properly; hence, to effectively heat or cool indoor air, the unit will be overtaxed, resulting in higher energy bills. To know whether or not your air filter is wasting energy, start by taking it out of the unit and see if it needs to be changed.

To find a new suitable filter, you’ll need to check the size written on your unit. If it’s not written, you can simply take a tape measure to know the length, width, and depth of the filter you need. You’ll probably find a filter on the market with the same size that you want, but there are also services that can customize your filter according to the size and material you want to use if you can’t find the size you need on the market.

If You Want to Ensure Optimum Health

The airborne pollutants may have long-term effects on your health. Because you can’t see them, it can affect your health and immune system without you even knowing. These contaminants may come from cigarette smoke, lead, pollen, and airborne chemicals. In addition to this, the effects of these particles are not widely recognized by the government regulators. In fact, only about a quarter of the number of chemicals used in the US has been tested for their effects against humans, so to ensure that you’re breathing high-quality air and not having to constantly fear for your health, consider purchasing a new air filter or an air purifier.

When You Start Getting an Allergic Reaction to a Seemingly Invisible Allergen

You might get an allergic reaction if the air you’re breathing is not properly filtered. There are a lot of people who experience allergic reactions to multiple allergens, such as smoke, dust or dust mites, fungi spores, pollen, dander, and much more. Unfortunately, these particles vary in size, which means that not all air filters will be able to block all of these particles out. Thus, if you notice an allergic reaction, you’ll have to check the MERV rating (Minimum Efficiency Reporting Value) of the current filter you’re using, as this will tell you the size of particles causing that allergic reaction you have. MERV ratings tell you the size of particles your filter can block out. So, if your filter has a MERV rating from 5 to 8, for example, that means that it can block particles bigger than 3 microns. If you’re experiencing an allergic reaction despite having that kind of filter, then you might want to use another one with a higher MERV rating. A filter with a MERV rating of 13-16 is the most effective and will block away almost all airborne contaminants.

Whenever You Notice Signs of Respiratory Problems

If you have asthma, or if you have just started noticing that you have respiratory problems, the first thing you’ll want to do is go see the doctor to ensure that your respiratory system gets the best treatment. The next step is to install an effective air filter in your HVAC system or use a top-notch air purifier in your house, your car, and, if possible, your workplace.

When it comes to buying a new air filter, you’ll find various options on the market, like HEPA filters, washable air filters, fiberglass filters, and polyester filters. Make sure to review their pros and cons, and take note of their MERV rating to know how efficient they are before making a purchase. This is, after all, a long-term investment, so you need to get the best product that you can get your hands on.
