Every home that has an HVAC system needs air filters, it’s practically a given. As their name suggests, air filters filter out the air that enters and circulates around your home, leaving you and your family with cleaner air to breathe. Just like car filters, these home air filters also need to be changed out every 3 months (or more frequently if you have pets or asthmatic family members). But what happens when you don’t change them out for months on end? 1. Frozen Coils The lack of airflow to the cooling coils or the evaporator can be caused by the air filter being too congested, which can happen during the summer cooling season. This, in turn, causes condensation to freeze and your coils and fans to have frost buildup, which can make it a lot more difficult for your air cooling unit to work by removing heat from air and cooling your home. If unresolved and kept as is for a long time, your air conditioning unit may even break down. 2. Mildew, Mold, and Bacteria Growth A clogged air filter could also cause the evaporator coil in air conditioning or heat pump systems to get covered in mold, bacteria, or dirt. When this happens, the critical heat exchange process is constrained, which gives your A/C or heat pump a hard time in effectively controlling indoor climate or removing ample amounts of humidity in the air. It also turns the evaporator coil into a sort of petri dish where microorganisms can multiply. 3. Poor Air Quality As its name stipulates, air filters filter out unwanted particles and bacteria from the air that you breathe in. Hence, if your system’s air filters are dirty and unchanged for months, you can bet that the air that you’re breathing in is dirty, too. Worse, a blocked air filter continuously re-circulates the particles that it normally should keep out of the indoor air, causing you and your family members to experience any number of symptoms including fatigue, allergies, and headaches. 4. Higher Energy Bills Your entire home’s central air conditioning system depends on the continuous re-circulation of air, so when that circulation is disrupted by a clogged or dirty air filter, you can expect your system to struggle just to continue cooling your house as normal. The harder the system works, the more energy it requires – which ultimately means higher energy bills, as well. In other words, you’ll be getting less air for the value that you normally would pay for clean air in the home. 5. Furnace Failure The worst scenario to your home’s HVAC system when you fail to change your dirty air filters would be to have it all stop working altogether. When you compare the price of having to repair or even replace your entire HVAC to the price of changing air filters every couple of months or so, the decision should be fairly obvious. FilterBuy's air filter sizes can even be ordered online and delivered to your home, which eliminates the need to head out to buy them. Changing air filters in your home’s AC and ventilation system literally takes minutes. So the next time you feel the need to put off removing your dirty air filters, think of what it would do to both your HVAC system and your family’s health.
Indoor air can be more polluted than the air that you breathe outside. Shocking, but true. And it isn’t just because you keep your windows open at night, thereby allowing the pollutants in outdoor air to waft into your house. Chemicals commonly found in each households, such as floor cleaners and insecticides also add to the growing list of pollutants that are making your indoor air quality bad. But while there are certainly dangers lurking in every room in the house, the good news is that there are affordable and easy solutions for most of them. 1. Increase ventilation. Ventilation should be a priority in every household. Not only does this allow fresh outdoor air in, it also lets the bad air inside the house out. Increasing ventilation promotes good air circulation and prevents molds and other harmful substances to grow and lurk within the confines of the home. 2. Keep your house clean. While good ventilation allows healthy air circulation, the dust and dirt that settle on the surfaces in your home throughout the day don’t really clean themselves up. Keeping the house clean not only involves dusting and sweeping, it also means taking out the trash to avoid the accumulation of bacteria that could become airborne, and keeping toxic substances away when not needed. 3. Turn on the air conditioner. It may come as a surprise to some, but turning on your energy-star-labeled air conditioner, especially in the summer, can actually remove particulate matter and pollen from the air. Air conditioners work by cooling the air and removing the water from the atmosphere, and as a lot of pollutants are soluble in water, they are also removed during this process when the air conditioner is working. 4. Install an air filter. For utmost protection against the negative effects to health caused by bad indoor air quality, having an air filter installed is the best solution. As their name suggests, these filter out particles of dust and other substances in the air, leaving the air that you ultimately breathe in cleaner than it once was. Good quality air filters, such as those from Filter Buy, can remove even very small particles, and are an especially great installation in households with asthma-stricken family members. Indoor air quality can be worse than the air just outside your home, but it doesn’t have to always be the case. By taking steps to clean, ventilate, and install air filters, having improved indoor air quality is not an impossibility.
