A Guide To Selecting A Portable Air Cleaner, Furnace Filter, Or HVAC Filter

The air quality indoors is frequently more polluted than the air outdoors, which can obviously negatively impact you and your family's health. Some of these pollutants originate from the outdoors, while others come from indoor sources and activities including cooking, cleaning, secondhand smoking, construction materials, consumer items, and home furnishings.

As a result, the best strategies to enhance indoor air quality are to reduce or eliminate sources of pollutants and to ventilate using fresh, outside air. Filtration has also been found to be a beneficial complement to source control and ventilation in studies.

You can use an air purifier or change the filter in your furnace or heating, ventilation, and air conditioning system (HVAC) if you're concerned about the quality of your indoor air. Portable air cleaners, often known as air purifiers or air sanitizers, are air cleaners that are meant to filter the air in a single room or area.

Meanwhile, an HVAC filter or central furnace will purify the air in every room of the house. However, when selecting an air cleaner, furnace filter, or HVAC filter, keep in mind the following:

  • A home air cleaner or filter cannot eliminate every air pollutant.

    The majority of filters are designed to filter either particles or gases. Therefore, many air cleaners contain two filters, one for particles and another for gases (inclusive of gases with odors). A typical air cleaner has only one filter, usually used for particles. Further, some air cleaners or filters are designed to target particular gases or VOCs. You can also check the specific product packaging or label for more information.

  • Replace all filters on a regular basis.

    An overloaded and dirty filter will not function properly. Air filters are things that are easily forgotten as they are usually tucked back into a closet or storage space. The key to keeping on top of regularly changing the air filters in your home is to set yourself reminders. Here are a few options:

    • Write the date you changed it on the edge of the filter.
    • Write the date to change the filter on the family calendar.
    • Set up automatic reminders on your phone.

When To Choose Portable Air Cleaners?

  • To Filter Particles in a Single Room:

    Choose a portable air cleaner with a clean air delivery rate (CADR) big enough for the size of the room or area where it will be used to filter particulates. The higher the CADR, the more particles the air cleaner can filter and the greater the service area it can cover. The greatest size area or room that an air cleaner should be utilized in is usually specified on the box. Often, portable air cleaners achieve a high CADR by using high-efficiency particulate air (HEPA) filters.

  • Choose To Filter Gases:

    Select a portable air cleaner with an activated carbon filter or another gas-filtering filter. As far as gas-removing portable air cleaners or filters are concerned, there is no commonly accepted performance rating system. Only particles are rated with the CADR system. If a considerable amount of material is utilized in the filter, activated carbon filters can be effective. With a portable air cleaner equipped with an activated carbon filter, particles and gases can be filtered.

In general, greater fan speeds and longer operating times will produce more air filters. When set at a lower speed, an air cleaner will not filter air. Since more air passes through the filter at higher fan speeds, higher fan speeds typically provide more filtration. A longer run time for an air cleaner will also boost filtration.

When To Choose Furnace and HVAC System Filters?

  • To Filter Particles Throughout a home:

    A furnace or HVAC system works to filter the air in the entire home, however, it works only when it is operating. Most HVAC systems only run during the heating season or cooling season (fewer than 25% of the time). It is more efficient to run the system for longer periods in order to get more filtration. The idea may not be feasible or desirable in many cases, since prolonged run times can lead to higher electric bills and also less reliable humidity control during the summer months.

  • Choose Only With 13 MERV Ratings or Higher:

    Filters for furnaces and air conditioners in houses are typically intended to filter particulates. Consider a filter with a minimum efficiency reporting value (MERV) rating of 13 or the highest rating the fan and filter slot of your system can support if you prefer to upgrade or use a higher class of filter.

In addition to filters, there are other devices that remove particle and gas mixtures. Usually, they are found in commercial buildings and large buildings with HVAC systems.
