Air Filters vs. Air Cleaners

Our highly climate-controlled indoor environments can often be incredibly comfortable in our modern world. Combine that with the fact so many of our daily needs are easily met without needing to go outside, and you find a society that spends nearly all its time indoors. As a result, poor indoor air quality has become a significant area of concern as a contributor to potential health problems.

Our team at Schar Heating and Cooling, along with many manufacturers of air filtration and air purification products, are working to provide tools to help you ensure clean indoor air for you and your family. Here are some details about currently available solutions.

Air Filters

Air filters are typically a part of your home’s heating, ventilation, and air conditioning (HVAC) system. Before circulating air enters your equipment to be heated or cooled, it passes through a filter to trap and remove a wide range of particulates. Keeping your air filter clean is the best, cheapest, and easiest way for you to take care of the air quality in your house and maintain your furnace. Change your filter all year around because central air conditioning also usually uses the furnace to circulate the cold air throughout your home.

Many different types of air filters are available, ranging from very basic and inexpensive to more costly versions that filter out microscopic particles. The experts at Schar Heating and Cooling happily help customers determine which is the best option for them.

An industry-wide rating system promoted by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) helps consumers compare one type of filter to another in terms of performance. A minimum efficiency reporting value (MERV) rating system measures a filter’s ability to remove particles from the air. Filters carry a rating somewhere between 1 and 16, with the higher values signaling finer filtration.

Air filters can be made of many different types of materials. You may have used a layered fiberglass filter that’s surrounded by a metal grate or a pleated polyester filter in a cardboard frame. These filters typically need to be replaced every one to three months. Thicker filters, like HEPA filters, are made of superior materials require less frequent maintenance and do a better job of filtering the air.  

Homeowners living in Ohio who have family members with allergies, asthma, or other respiratory illnesses may want to consider using a high efficiency particulate air (HEPA) filter. These filters capture 99.97 percent of all particles 0.3 microns or larger. The National Air Filtration Association (NAFA) specifies six different levels of HEPA filters.

Air Cleaners

Air cleaners are often used in conjunction with HVAC-related air filters. These can be separate appliances typically designed for a single room or a certain square footage of space. Other air cleaners serve the whole house by attaching to the HVAC system. Schar Heating and Cooling specializes in installing several which effectively kill bacteria other pathogens.  Our customers have found significant improvement in their indoor air quality after installation. A wide variety of different technologies and systems are available to tailor to your needs.

For example, home ultraviolet (UV) air cleaners were developed from purifiers used in hospitals for disinfecting the air. These tackle bacteria, viruses, mold, and other pathogens.

On the other hand, activated carbon filters are very effective in removing gasses, odors, smoke, and other particles.

HEPA air purifiers work in a similar way to HEPA filters and remove dust, pet dander, pollen, and mold spores from your indoor air. Although HEPA air purifiers are effective at filtering out very small particles, they are unable to remove bacteria and viruses. Combining the HEPA air purifier with a HEPA filter would be a great potential solution.

Another type of air purification technology is using ions. These purifiers emit negative ions into your living space, which attract positive ions like dust. If the purifier is a small freestanding unit, the resulting particles become heavier and land on your home’s flooring or other surfaces to be collected during vacuuming and dusting chores. Remember to use a HEPA vacuum bag to maximize the capturing of the resulting particles. The best kind of ion purifier is installed in your HVAC system so the particles and dust are all filtered out on your furnace filter.  This “no extra work required” purifier keeps your house cleaner and chores easier while you enjoy living in your healthier environment.

Although all of these air purification systems typically work in a single area or confined space,  you can invest in house-wide purification systems as well. For instance, electronic air cleaners work with your HVAC system by employing static electricity, HEPA filters, and ionic cleaners in a single system. Centralized air cleaners can be installed as part of your ductwork and can complement your HVAC filtration system, and air-to-air exchange systems will allow you to pull in more fresh air from outside. The team at Schar Heating and Cooling would be honored to help you live a safe, comfortable, and healthy life!
