Air Purifier VS Fan: Can I Run Both At The Same Time?

There are a lot of myths surrounding an air purifier and fan. None more so than running an air purifier with a ceiling fan at the same time. Many people are concerned about the overlapping moving air pressure generated from both devices. This post will address it all, including the difference between a regular fan and an air purifier, the similarity, how they work, and the pros/ cons of running them simultaneously. As a bonus point, we will even throw in which devices to buy if you have to pick one. Let us begin.
Short answer
Air purifier + Ceiling fan = Good


Can I Use An Air Purifier And A Fan At The Same Time?

Yes, you can use an air purifier and a fan at the same time with no drawbacks. Both complement each other to provide a healthy and comfortable environment. A fan will help move and distribute clean air released from the air purifier. The increased air circulation will boost filtration efficiency, particularly during the winter when the air is cold and dense or on a small air purifier with a limited airflow delivery rate. The only condition is the air purifier must be well-maintained with clean filters. Otherwise, it will be counterproductive as the air purifier will stop working while dust particulates continue to linger in the air.

Air Purifier VS Fan

An air purifier and a fan are not the same even though both move air. Both are different appliances with different designs and functionality. Air purifiers remove airborne particulates and circulate clean air back into the room. It will not cool the room because of the slow-moving air. On the other side, a ceiling fan cools the room with its fast-spinning curved blades. It will not clean the air because of the positive air pressure that pushes air out rather than drawing in. A fan also does not contain filters to trap airborne contaminants.

How Does A Fan Work?

A centrifugal and axial fan makes the air feel cooler through convection and evaporation. Electric current passes through the copper windings; the fan motor turns the impeller connected with curved blades to create air pressure and airflow. The fast-moving air removes the warmer air from direct contact with the skin, increasing the convective heat transfer and cooling us down.

Convection is the movement within a fluid where the hot air becomes less dense and rises; cold air becomes denser and sinks due to gravity. Our body will sweat as part of the self-regulation, cooling process. Sweat consists of 90 percent water will start to evaporate from a liquid into vapor. The ceiling fan can hasten the evaporation process of transferring the heat out.

How Does An Air Purifier Work?

Air purifiers are electrical devices with a built-in electric fan to draw air into the filtration. Air that contains dirty particulates will be forced and trapped through a series of filters, leaving only clean air back into the room. In typical fashion, you have a washable pre-filter that traps larger particles like dust, hair, lint, and fiber while protecting the inner filter from being damaged. The denser, glass-threaded HEPA filter trap 99.97% of microscopic particles as small as 0.3 microns, including mold, pollen, pet dander, bacteria, and viruses. Activated carbon filters made out of many porous charcoals absorb smoke and odor substances, including VOCs, radon, cigarette, and chemical fumes. Other filtrations, including UV-C light, use ultraviolet radiation to kill biological pollutants. The negative ion generator diffuses millions of negative ions to adhere to positive ions particulates, causing them to fall from the air. There are also the EPA disapproved, dangerous ozone generators that we will not pay any attention to.

Which One: Air Purifier Or Fan

Get an air purifier if you have breathing issues or are allergic to airborne particulates like mold, pollen, dust mites, or pet dander. An air purifier will alleviate allergy symptoms like cough, nasal congestion, headache, itchy skin, throat, and eye irritation. An air purifier should also be your utmost priority for those who have asthma, baby, children, or elderly at home. Get a ceiling fan to lower room temperature, particularly for those that live in a hot climate area all-year old. There is no harm in getting both as they serve a different purpose. Alternatively, you can get an oscillating fan air purifier like Dyson to cool and clean air simultaneously. A space-saving, expensive product that has the best of both worlds.
