Does A Small Air Purifier Work In A Large Room?

Since you are looking to choose an air purifier for your large home or office space, the question might arise regarding its size. Here are the factors that determine whether a small purifier will work for a large room or not.

Coverage:

Smaller air purifier units usually come with limited coverage space of around 100 sq ft to 350 sq ft. While these are good numbers for your average-sized kitchen and living rooms, they fall short for bigger spaces. Thus unless you have a pocket-sized dynamo cranking massive power, it better to go with slightly larger ones that offer around 1000 sq ft to 1200 sq ft of coverage.

Placement:

Placement plays a major role in determining the effectiveness of your filtration device. Regardless of the size, your purifier may come with a single direction or a 360-degree filtration design. Thus you have to be careful in the option for a plugin place for the device to let it operate at full flow.

Filter Size:

It’s ultimately down to the filter that makes the purifier work. Small and handy units are great for portability but they have smaller filters that become clogged over extensive use. As a result, you may have to clean or replace the filters more frequently if you intend to use a smaller purifier for large spaces. Bigger units on the other hand have large filtration surfaces that can hold more dust offering more service periods.

How We Reviewed?

We went really crazy with this one. We visited a few nearby offices and neighbor houses and took measures of pollution levels. The results left us astonished. Nevertheless, the experience came in handy narrowing down our initial list of 58 models from amazon. It took around 43 hours plus the added time of our little office adventure mentioned earlier. These air purifiers can clean sweep spaces of 1000 sq feet without even flexing their muscles.

What To Consider Before Buying An Air Purifier For Large Room

Clean and fresh air is vital for a pleasant and productive day. Besides, with pollution on the rise, it’s high time to be concerned about the airborne diseases that might prove to be deadly. Here are the key features you need to look for while opting for an air purifier for extended rooms and office spaces.

Consider Before Buying An Air Purifier For Large Room

Coverage Offered:

When it comes to large spaces, the first thing that you must ensure is the coverage. It is good practice to take a measure of the space you are looking to purify. Being said, you can expect decent service from devices offering coverage anywhere between 1000 to 1500 square feet of space. This will offer you plenty of versatility in shuffling the purifier among home, office, shops, and basement setups.

Purification Tech:

One of the most important aspects along with the coverage is the filtration system and tech used in the purification process. Most of the advanced devices come with a pre and True HEPA filter combo as the base. Activated carbon layers and other odor elimination technologies offer an all-around purification and thus offer better value for the price.

Speed Settings:

You don’t want your purifier to run at full throttle all day when the air is relatively clean. Multiple fan settings come in handy in such situations that let you save up power and reduce electric bills. Air quality sensors aid the process and let your device manage fan speed on its own suitable to the pollution level. Besides lower fan speed modes emit less sound and preserve the ambiance for sleep or work.

Maintenance Cost:

Few purifiers come with efficient motors that have been tested to consume lesser power. These motors contribute to a lot of extent in bringing down the operation cost without sacrificing performance. For better mileage out of filters, you can look for washable ones. These washable filters may not retain their full potential, but will certainly get the job done.

Frequently Asked Questions

Here are answers to a few of the most common questions regarding purifiers that might come to your mind. So have a quick look at these before you go hunting for the best air purifier for large rooms.

Are air purifiers a waste of money?

No, they are not. Air purifiers have been tested to enhance air quality and thus offer a healthy surrounding to breathe in.

Is it OK to leave the air purifier on all night?

Yes, it’s completely fine as long as your purifier has fan adjustments sensors or sleep mode. These features are provided to ensure pleasant bedtimes.

How long does it take an air purifier to clean a room?

It depends on the purifier strength and room size. Any powerful purifier can clean a room of 350 sq ft once in about 15 to 20 minutes.

Final Verdict

This rounds up our discussion for the best air purifier for 1000 square feet. While all of these offer excellent value for the price, it’s your requirement that will help you finalize the deal.

As far as space is concerned, it’s always better to have plenty of coverage under the belt. Thus I would like to recommend the Bissell air400 Professional Air Purifier. It offers a hefty range of 1200ft² and an elegant design. Besides the smart PM 2.5 sensors add a whole dimension making it an effortless experience to operate.
