Is It Ideal To Use Air Purifier And Fan At The Same Time?

The benefit of running an air purifier and fan at the same time is a common topic when discussing indoor air quality. Do these devices complement each other’s functions? Or is it detrimental to run both at the same time? In this post, we will answer this and provide additional tips to increase the cleanliness of your indoor air.

Take note that air purifiers are fans to some extent. After all, it has a built-in fan inside to suck in air and force it into the filter. However, these fans have varying speeds and the ability to collect air from the surroundings.

This is why many users are wondering whether running separate fans can give air purifiers a boost. Overall, the answer is both yes and no depending on how it’s used and where the devices are placed. We also discussed further how fans affect air purifiers when used simultaneously.

Air purifier and fan at the same time, is it ideal?

Running an air purifier and fan at the same time can be useful on specific occasions. It can be beneficial, especially if you also want to boost air circulation and ventilation all at once.

It’s important to understand how these two devices work individually. Both have a fan mechanism, but the difference is that air purifiers pull in the air while fans blow it outward.

Aside from that, fans don’t have filters, so it doesn’t contribute to cleaning the air. Meanwhile, it is air purifiers that do the job of trapping airborne particles.

So what happens if you run them together? Here are the possible upsides and downsides:

1.    Fans help boost the air purifier’s functions.

Ceiling fans can boost the air purifier’s functions by increasing airflow. This is more useful during winter when the air gets really dense and the purifier has to compensate to suck it into the filters.

In this case, a fan can help move the air in the direction of the air purifier. Through that, the fan helps push the air toward the air purifier and the latter will perform all the cleaning.

Moreover, a fan will help compensate if you have an air purifier with a weak built-in fan. This way, you can speed up the air cleaning in your room.

2.    Fans can help dry up moisture.

Aside from that, using a fan while running an air purifier will help dry up moisture. This is possible because electric fans increase ventilation.

While electric fans aren’t dehumidifiers, they can help disperse airborne water vapors out of your room. You can do this by opening the door of your room.

However, you should avoid opening a window while an air purifier and fan are running. Although this will help in drying up moisture, outdoor pollutants can get sucked into your house as well.

3.    Fans help spread clean air evenly.

Using a ceiling fan while an air purifier is on will spread clean air throughout your room. This way, the dirty air will also reach the purifier for efficient cleaning.

Overall, this benefit is more observed in large rooms. Aside from using a fan, you can also add another purifier to cover more ground in terms of cleaning the indoor air.

4.    Fans are helpful, but not always necessary.

In the end, fans boost the functions of air purifiers, but it’s not a necessity. For one, modern purifiers are equipped with fans and turbo mode that allow them to draw in large amounts of air in a short period.

If your purifier is powerful enough to trigger enough air circulation, using a fan is no longer necessary. Nevertheless, there’s no harm in experimenting and seeing what works for your home best.

How to make your air purifiers work better

Air purifiers are designed to remove pollutants from the air. But for it to be efficient, proper maintenance and usage on your part are necessary.

Here are some of the steps you can take to ensure that your air purifier is always in its top shape:

1.    Match it with the room size

First, it’s important to get an air purifier that matches your room’s size. Big rooms require equally large units to ensure efficient purification.

This way, the unit will be efficient in cleaning the air. It will also speed up the process compared to using purifiers that are much smaller than what your room requires.

2.    Replace your purifier filters regularly

Take note that the filters of air purifiers need to be replaced based on the manufacturer’s recommendation. Most of the time, purifiers are fitted with a HEPA filter that needs to be replaced every 30 to 90 days.

Remember that HEPA filters aren’t washable. It’s because moisture will negatively impact its ability to filter pollutants.

Always check the instructions on the purifier manual to know how often you need to replace the filters and what type it uses.

3.    Be smart with the purifier placement

Also, make sure that you place the air purifier in a strategic spot in your room. As much as possible, try to place the appliance near the middle for even air circulation.

Aside from that, you should direct the airflow into your breathing zone. This way, you will receive clean air right away. Overall, this wouldn’t be an issue if you’re running the purifier all day long.

4.    Close doors and windows

When using an air purifier, you should close all windows and main doors. This is to prevent pollutants from being sucked into your home. Closing your windows will ensure that only the indoor pollutants will be removed and you’ll enjoy clean air.

It’s also important to patch holes on your walls or window frame. Aside from preventing pollutants from entering, this will also come in handy when using your air conditioner or heater.

5.    Avoid ozone-generating purifiers

When purchasing an air purifier, avoid those that generate ozone. This reactive gas can cause asthma attacks and respiratory distress.

Shady manufacturers will often hide this by branding their purifiers as an ‘ionic’ type. Most of these ionic purifiers release ozone, which is harmful to your health.

The best option is a HEPA filter air purifier. This will eliminate harmful pollutants without releasing any harmful substances or gasses.

6.    Invest in a durable unit.

Lastly, always put your money on a reliable air purifier. While cheap ones are affordable, most of these will not last for years. Also, it may not purify the air as much as quality models can.

So if you want an air purifier that works well, you should invest in a premium model. It will pay for itself in the long run as you enjoy clean air and fewer irritations.
