7 Best Air Purifier for 500 Square Feet
Most of the air purifiers in the market today are designed especially for small and medium-sized rooms. But what to do when you have ample space in your house-sized between 300 to 500 square feet? Or what if you are looking for air purifiers for the large conference hall in your office? No worries, because I got you covered!
When you have a room exceeding 300 to 500 square feet, it means there is a massive area for airflow. And to keep the air clean and fresh in such a large room, you will require an air purifier with some muscle.
It means you need something with a lot of fan power to suck in a considerable quantity of pollutants and dirt particles, and it should be able to do it effectively.
But at the same time, you must know that many manufacturers compromise the quality and strength while building units for 500 square feet while referring to their more powerful air purifiers.
What you get at the end are weaker versions that claim to offer clean air but are unable to do so.
Here is a list of the top 7 air purifiers which are perfect for larger-sized rooms up to 500 square feet.

1. MSA3 Air Purifier for Home
- Cleans rooms up to 840 ft²
- 3-in-1 True HEPA Filter
- Filtration Performance
- User-friendly Design
- Safe and Reliable
The design of this air purifier is very smooth and clean and comes in a standard white color. The machine contains a HEPA filter, making it very efficient to draw in polluted air and expel fresh and clean air.
Talking about functionality, it is a straightforward device, but a fair degree of thoughtfulness is added to it in terms of interaction with the controls. Turning on the Turbo mode will switch to the highest fan speed.
There is also a Sleep mode button using which you can switch the fan to its lowest speed while turning off the lights simultaneously.
You also get a timer using which you can schedule up to 8 hours of operating time before the machine shuts down automatically.
However, you cannot turn off all the lights unless the entire device is totally off. There will be one tiny light that will be on constantly, but it’s hardly distracting.
There is also a lock button to prevent your curious toddler from pressing all the buttons. A filter reset indicator is also present in the device, letting you know whenever you need to replace the filters.
The MSA3 uses a classic 3-in-1 filtration system. At first, you have the pre-filter, which helps trap bigger harmful particles like hair, pet dander, fur, etc. The next is the True HEPA filter which is the most essential and can capture dust, smoke, pollen, and other microscopic particles as small as 0.3 microns.
Can you get an activated carbon filter that helps absorb foul odors, pet odors, VOCs, smoke from cooking or tobacco, etc?
The sound level is also relatively low, ranging from 43dB to 55dB. Overall it performs well in cleaning those allergens, dust particles, and pet dander to give you better indoor air quality.
Pros.
- Suitable for medium to larger-sized rooms.
- 3 in 1 filtration system.
- True HEPA filter.
- Low operating sound.
- Child lock feature.

2. Medify MA-25 Air Purifier

The Medify MA-25 does not have any significant flaws and is also one of the rare budget air purifiers with a tempered glass panel.
This one in the race for the best air purifier for 500 square feet has a rectangular body, and the design is somewhat familiar to a lot of Korean air purifier models. It is compact and has decent airflow.
Coming to the filtration system, the air purifier uses a 3-stage system consisting of a pre-filter, a True HEPA filter, and an activated carbon filter. The pre-filter covers the HEPA filter and traps large pollutants like large dust particles, pet hair, fur, etc.
The HEPA filter can capture 99.97% of particles as small as 0.3 microns. These particles include dust, virus, mold, and fungi particles. An activated carbon filter uses carbon pellets to absorb unpleasant odors and other gases.
One of the significant disadvantages of using this purifier is that the replacement filters have a high annual cost. It can be used in a room has 500 square feet size. However, the machine performs even better in smaller-sized rooms.
The noise level is relatively low, and even at the highest fan setting, it reaches only 51dB. The power consumption of this cleaner is only 25 watts, and it is an Energy Star-certified product.
There are a few additional features that the device flaunts. There is a dimmer setting to help you arrange your environment to have complete darkness. You also get a timer setting to schedule the runtime of 1, 2, 4, or 8 hours, after which it will shut down automatically.
You get a child lock function and an LED indicator for filter replacement. There are no innovative features, and if you are looking for high-end functionality, I recommend you to look for the Medify MA-Smart range.
Pros.

- Dimmer option and filter reset indicator.
- Lifetime warranty.
- The glass panel gives a premium feel.

This purifier is absolutely packed with power and offers high-end cleaning performance. It can easily cover rooms of up to 525 square feet, but it is indeed slightly on the higher price end. But the cost justifies its capability to do its primary job- and that is to filter out the pollutants and keep your air fresh and clean.
The CADR rating of the BLUEAIR 211+ is also a big, fat 350, and it speaks volumes about its performance. The device is pretty simple to use as you can turn it off or on with just a single button. It is lightweight and portable. But you do not get an automatic off-timer, which was expected at this price range.
It is Star Energy rated, which means that the energy consumption is relatively low (30-60W). The pre-filter is made of washable fabric to capture larger airborne particles. The HEPASilent filter removes 99.97% of the pollutants as small as 0.3 microns. The activated carbon filter helps absorb volatile organic compounds resulting from chemicals used in houses like cleaning products or paints.

The Honeywell HPA5300 deserves a spot on this list as it is one of the most powerful air purifiers I have come across. The machine has a CADR rating of 323 CFM for tobacco smoke and is suitable for rooms up to 500 square feet in size.
If you use this in smaller rooms, this air purifier can filter the air even faster. A special feature of the Honeywell HPA5300 is that it sports a VOC sensor to detect chemicals and odors in the air and adjust the fan speed automatically. Moreover, if you want to change the fan speed manually, there are four different levels to choose from.
