Which is the Best Large Room Air Purifier in the Market Today?

Are you looking for the best large room air purifier? You’ve come to the right place – we’re giving you tips on how to choose one, as well as a couple of suggested units we’d like you to try.

Air purifiers come in all shapes and sizes – some are best for small rooms while others are for the larger, more spacious places. If you work in an office room with lots of employees and want to maintain clean air all throughout the place, having a large room air purifier can help do the trick.

The same goes for when your living room is spacious – using an air purifier that’s only meant for small rooms may not be that effective (and could even ruin the motor of your unit). Therefore, it’s more sound to invest in an air purifier that’s going to do the job smoothly for larger rooms.

Will a small air purifier work in a large room?

Yes, it can, but it depends on its specs. An air purifier’s power is not always measured by its size – it is rather measured by its clean air delivery rate or CADR, as well as its room rating and fan speeds.

For example, the SilverOnyx Air Purifier is rated for up to 500 square feet of room space, yet it only takes a small amount of space in your table or working desk!

This air purifier has more than just a true HEPA filter and a mesh pre-filter – it also has an activated carbon filter to take out bad smells and a UV-C light lamp to sanitize your home against mold spores. It even has an ion generator (doesn’t have ozone) for additional air sanitation.

Always remember to look into the specifications of an air purifier before you buy, then match it with your room or office. Just because a unit is small doesn’t mean it can’t tackle large rooms when it has a powerful motor and inner workings to freshen your air.


Are room air purifiers effective?

Yes, they are! Here’s why they can be worth investing in:


  1. They help remove odor. Did you know that you can use an air purifier for cooking smells? Yep, thanks to their activated carbon filter, air purifiers can neutralize and minimize food smells, cooking smells, tobacco, pet odor, and other nuisances.


  1. They reduce indoor pollution. Simply put, they use their true HEPA filter to capture pollen, allergens, and other floating items in the air that’s hard to catch using your vacuum cleaner alone.


  1. They can help disinfect your home. Does an air purifier help with mold? Absolutely – if it has the right type of filters. UV-C lamps, when used with your two main filters, can kill germs, viruses, and mold spores.

Where is the best place to put an air purifier in a room?

It really depends upon what type of air purifier you have. There are many kinds of air purifiers depending on their design and shape, such as the following:


  1. Tower air purifiers. These are common in the market because of their size. They are best used in rooms that do not have a lot of circulation or don’t have a lot of windows and ventilation from the outside. One such air purifier would be the Germ Guardian True HEPA Filter Air Purifier.


This mold-killing device not only filters pollen and allergens with its true HEPA filter but could also eliminate mold spores and germs with its UV-C light. It may also help remove bad smells with the activated charcoal filter. And since it has a tall tower design, it can cover your room more effectively than most unit types.


  1. Canister air purifiers. Unlike tower air purifiers, canister ones are cylindrical in shape. They take up less space so they are best used in homes that are not so spacious. For instance, you can use it in an apartment, a condo unit, or a single room. You can also use these air purifiers in your cubicle or work desk and it won’t be much of a bother.


The typical notion is that canister air purifiers are meant only for small rooms. However, there can be large-room units out there (such as the SilverOnyx that we mentioned earlier) because they have specs that can compete against larger units in terms of cleaning up the air of spacious rooms.


  1. Rectangular units. These are also very common and can be placed near walls. They tend to be either flat or box-type depending on the unit that you have. If they are flat, they are usually placed on the wall so that they don’t take up too much space. Other air purifiers can even be stuck to the wall for a more efficient cleaning method.

However, as a general rule, air purifiers are best placed in the room (or portion of the room) that smells bad. Or, you can place it near the windows or ventilation areas so that air can be filtered out as it goes in and out of your house.

You don’t have to spend too much to buy a decent air purifier for the job – it’s just the matter of reading the specs of the unit before you purchase one. We hope you liked our suggestions!
