    Room Air Purifier?

    Hey guys, I was wanting to get some of y'all thoughts on decent room air purifiers. We have a habit of sleeping with a fan running for white noise. I figured instead of running just a regular isolation fan mixing the air up, we could run an air purifier to help filter the air making our IAQ a bit better. Any thoughts is greatly appreciated thanks...

    They can make a big difference. I wouldn’t hesitate shopping for one but get one that you can easily replace the filters.

    If you want the white noise, then an air cleaner can be a good thing. It won't cool you off like a ceiling fan, but it will deliver clean air and provide some white noise.

    Generally speaking, look for a HEPA-based air cleaner and skip the other gimmicks (e.g. ionizer, ozone, cold-plasma, etc). Ignore air cleaners claiming to perform better than HEPA. Even if you could outperform 99.97% efficiency for all sized particles (as a HEPA does), the incremental benefit wouldn't have any clinical significance.

    You could aim to get 5 air changes per hour from the unit. Buy one with a published clean air delivery rate (CADR), typically measured in cfm (cubic feet per minute). Then do the math to see if you get 5 air changes per hour. I can explain the math if people are interested.

    I think this buddy will do his job perfectly!

    The German manufacturer ALLROLL GERMANY GmbH is well known in the market, and its devices are used all over the world.
    ARP-420 H is a fairly large air purifier, 60.3 cm high and 10 kg in weight, but this is compensated by functionality and modern design. Firstly, ARP-420 H - provides 8-stage air purification due to 3 sets of filters: a pre-filter; HEPA filter; activated carbon, zeolite, and cold catalytic filter. As a result - almost complete retention of dust, allergens, pollen, and fine suspended particles, as well as neutralize odors and harmful gases. This air purifier is equipped with an ultraviolet filter and an ionizer, with an additional humidification function.

    Secondly, this device has a high capacity of work СADR 420m3 / hour and, at the same time, is energy efficient. It is able to clean the air in a room up to 50 sq. Thirdly, the ARP-420 H has many additional functions that make it more comfortable to work with: a control panel, a digital panel, a night mode, a four-color air quality indicator, an automatic air purification mode, and a timer, as well as a child lock.
