The right HVAC filters can make the difference between air that is clogged with contaminants and air that is clean and healthy to breathe. It is essential to consider all options when selecting an air filter. Do you have pets that shed their hair? Does anyone in your family suffer from environmental allergies? Generally, more expensive air filters are more effective, but a single person without pets and allergies may not need as much filtration as a family of five with three pets and a child with asthma. How can an air filter make such a difference? A dirty or damaged air filter restricts the amount of air that flows into the engine, causing it to work harder and consume more fuel. Since the engine needs more than 10,000 liters of oxygen to burn every liter of fuel, it is important not to restrict this airflow.
If all dimensions are the same, a filter with a higher MERV rating and more folds per inch will have the same or better airflow than the same filter with a lower MERV rating and fewer folds. An electrostatic air filter is a washable air filter that uses static electricity to capture particles. This is especially true in homes with older HVAC units, which weren't designed to accommodate thicker air filters. In addition, pleated filters do not need to be changed as often as non-pleated filters - once every 3 months instead of once a month. If your vehicle doesn't come standard with a high-flow air filter, replacing it isn't part of your regular maintenance, but there are still some reasons why people decide to invest in this basic and easy modification.
Fuel economy has been improved because high-performance air filters draw air from outside the engine compartment, where the air is colder. The experts at David Gray Heating & Air have extensive experience and knowledge to help you with your air filtering needs. Doing so will likely create airflow issues that increase utility costs and decrease blower life in the central air unit. When it comes to the health and comfort of your family, friends, and other guests, it's wise to get the most efficient air filter you can afford. Look at the label and note the manufacturer's recommendations for how often you should replace the filter. When comparing the cost of a pleated filter with a non-pleated filter, you have to triple the price per filter of the non-pleated filter to get an accurate comparison.
Air filters remove particles of different sizes from the air before it flows through the blower to the rest of the house. Air filters are also important for people who live in highly polluted areas because they can filter out harmful contaminants from the air. That's why it's important to use only air filters with the MERV rating recommended by the HVAC system manufacturer. When most people talk about electronic air filters, they usually refer to an air purifier or an electrostatic air filter. Household HVAC air filters are rated based on their MERV rating, with most household filters between 1 and 13 (more than 13 are for HEPA filters).
