Understanding HVAC Filters

Good Deals Heating and Cooling HVAC FilterMany people find HVAC units pretty intimidating. After all, they are big pieces of equipment, and since they need to be fitted by a professional, most assume that any additional work, including changing the filter, also needs to be done by an expert. Others still are confused about how often they need to change their filters, and as a result, they never bother to change them at all- meaning the filter won’t work properly. This article will help clarify some of those issues and explain MERV (Minimum Efficiency Reporting Value). MERV is the standard by which the effectiveness of HVAC air filters is measured. The higher the MERV value, the better the filtration, which means small particles of dust and other substances are less likely to pass through the filter. MERV values range from 1 to 20, and filters rated between 8-13 are powerful enough to keep the air in your home nice and clean. Anything above that range is usually intended for use in hospitals or other healthcare facilities, so there’s no need to spend the extra money for something that won’t have much of an impact in the average home.

However, filters with higher MERV ratings need to be changed more frequently to keep them working to their full potential. If you don’t change it often enough, the filter will start to become clogged, and stop filtering out particles. The recommendation is to change the filters every three months.  Changing filters every two months will provide superior filtration. One exception to this rule is during the summer when the unit will be operating at full capacity. During this period, it’s advised to replace the filter every month.

Measuring the size of filter needed is easy.  Take a tape measure and measure the length, width, and depth of your filter.  These measurements are all you need to find the right size.  Changing the filter is also a simple job- just make sure the HVAC unit is turned off before you start. If you’re not sure how to do this, then it’s best to shut down the breaker to be on the safe side. Most HVAC units have the filter situated at the bottom or right-hand side of the unit. Pull out the old filter, and then slide the new one in- easy!

Filter Bad Health From Furnace Heating

Good Deals Heating and Cooling furnace heatingFor those with hay fever and other allergies, the summer months can be a nightmare. You can’t go outside without the allergies acting up leaving you with a runny nose and itchy eyes. However, did you know that if you’re not taking care of your furnace and heating ducts, they could be collecting pollen that will cause you headaches come fall?

Furnaces use “forced air” to heat your home, but if pollen has built up in the ducts over the summer, it will be propelled out into your home by circulation fans leading to your personal hay fever season. One way of solving the problem is to have your ducts cleaned each fall, but this can be an expensive, time-consuming process which would need to be done each year. You might want to be out of the house while the furnace heating cleaning process takes place, after all, it’s likely that more than a few pollen particles will be expelled into the air, which is what you’re trying to avoid in the first place.

If you want to save money in the long run, then a more practical solution is needed. The best way of doing this is to install a permanent HEPA filter, which will filter out up to 90% of particles, and do a much better job than temporary filters. Of course, HEPA filters still need to be cleaned from time to time, or else dust and other particles will block the air flow, but this is a simple task, and a lot easier than cleaning out the air ducts.

To keep your permanent HEPA filters squeaky clean, you can even fit them with a special additional fabric filter mounted on the outside of the duct. This extra filter helps keep the dust and pollen particles from even getting into the heating system so that you can enjoy clean, warm air all the way through the fall and winter. This filter system also stops pollen from getting into your home during the summer, dramatically cutting down on the symptoms of hay fever. If you want to stop waking up every morning through the summer with your eyes watering and your nose running, and avoid prolonged symptoms when fall comes around, then it’s time to filter bad health from furnace heating today!
