Yes, you can use an air purifier and a humidifier side-by-side in the same room. The air purifier will clean the air of pollutants while the humidifier adds moisture back into the air to make it more comfortable to live and breathe.
Similarly, you may ask, can you use an air purifier and humidifier together?
You can safely use both an air purifier and a humidifier together because they do very different things. Air purifier/humidifier combo devices also exist if you want to invest in such a machine. While your humidifier raises the moisture level in the air, the air purifier will work to clean out the contaminants.
Subsequently, question is, do I need a dehumidifier if I have an air purifier? It depends. If you want to get rid of dampness and a musty odor, then it’s best to use a dehumidifier. If you want to have clean, fresh air to breathe, then use an air purifier.
Also Know, is it OK to leave air purifier on all night?
This also means that you should run your air purifier all day and night long without turning it off. The reasoning to this is very simple as clean air will get contaminated again within 3-4 hours time if you had left your air purifier turned off. Therefore, it is highly advisable to run the air purifier 24 hours a day.
What happens if you put a humidifier and a dehumidifier in the same room?
The dehumidifier would win the the end because the humidifier needs fuel (water) to work. But in the long term, of course, the dehumidifier works because the humidifier can only put as much moisture into the air as you put in there.
