Best Air Purifier For Large Room Coverage Reviews

Large Air purifiers are the best way to keep the air in your home clean. Don’t let the terminology fool you; air purifiers and air cleaners are the same thing. They eliminate pests, toxins, and allergens from the air and are effective at preventing allergic reactions. There are lots of benefits to getting a Large air purifier, but the only way to enjoy those benefits properly is to get the right one for you. Here’s what to look for when buying a large air purifier.

What to Look for When Buying a Large Air Purifier

  • Air Cleaning Technology

Air purifiers use four primary kinds of cleaning technology; mechanical filtering, electrostatic air cleaners, ion generators, and there are hybrid systems that combine different technologies. Each system works differently but it has the same goal; cleaning air by eliminating particles caused by smoking, fumes, pollution, pollen, dust, allergens, and other airborne irritants.

  • Filter Type
  • HEPA (High Efficiency Particulate Air): remove lots of dust, animal dander, dust mites, and pollen. True HEPA is considered to be 99.97% efficient. If you are going HEPA, make sure to look for a True HEPA filter. Another thing to consider with HEPA filters is that they have to be changed annually, so factor in the cost of replacement or find a model that can be re-used. It’s also worth noting that HEPA filters are considered the best for removing allergens. If you want a filter to reduce allergic reactions, you want a HEPA filter.
  • Charcoal/Carbon filter: Charcoal and carbon filters work to get rid of larger particulates such as smoke and odors. These filters are often built into HEPA and ULPA filters, but can be found separately.
  • Air Change/Efficiency Rate (ACH)

The ACH Rate – also known as the Air Change Per Hour rate – indicates how often the air purifier cleans the air in a room across an hour. A rating of 2ACH would mean the air is cleaned once every half hour, while a 4 ACH rating means the air is cleaned once every 15 minutes. The highest possible ACH rating is six.

  • Room Size

The size of a room is an important consideration, especially when choosing a large air filter. The larger the filter is, the more room it can cover. It’s worth measuring the size of the room in question and finding a filter that is designed to work with a room that size. Larger air filters are more expensive. You don’t want to be paying for something that you don’t need.
