If selection is important to you, go for a honeywell purifier. This flow through humidifier may not be as easy to install as Honeywell claims. Nonetheless, this device strikes an impressive balance between quality and value. Depending on where you live, the installation will likely run you between $50 to $70 per hour. In most cases, the installation can be complete in a couple of hours.
The user manual advises against putting the humidifier on any surfaces that can be damaged by water and also suggests placing it at least 12 inches away from any walls. The Vornado UH200 Ultrasonic Humidifier feels (and sounds) like an honeywell air purifier evaporative one, and it’s particularly great for larger spaces. It offers the same steady humidification as our other Vornado pick, along with a larger tank and warm-mist capabilities, and it has one of the best warranties we’ve seen.
Since 2013, we’ve spent nearly 500 hours researching and testing dozens of humidifiers in enclosed home spaces, using Lascar data loggers. Senior staff writer Tim Heffernan took over in 2017, building on that earlier research. Tim has also written guides to air purifiers, water filtration systems, and more. Since 2019, the guide has been shepherded by staff writer Thom Dunn, whose other work includes guides to space heaters, portable air conditioners, and window air conditioners. If you’re looking for a unit you don’t have to refill so frequently, you may opt for another brand.
It’s a basic humidifier with very simple controls, but has two large water tanks and can quickly raise the humidity of large rooms. It’s worth reiterating that warm-mist humidifiers have the potential to cause some serious burns, which is why the Mayo Clinic recommends against using them around children. They also use a lot of energy—more than 10 times as much as cool-mist models do. But we know some people still like the option (and even we admit that it can be nice sometimes).
We’ve been recommending the non-smart version of this Levoit since 2018, and this new model addresses every minor gripe we had with the old one and more. The Levoit LV600S is powerful, quiet, and easy to clean, and it offers Wi-Fi connectivity and warm-mist capabilities. Plus, it’s the rare ultrasonic model that won’t over-humidify your room. Shop Honeywell Home humidifiers to help balance the humidity levels in your home for optimum comfort.
The updated version of the Honeywell Replacement Filter A features a blue pre-filter layer that helps capture large airborne particles from the air that passes through the filter. A fan sucks dry air in from the room, passes it through the filter, and pushes hydrated air back out. The filter is easy to remove and put back in — you simply lift off the top of the humidifier, pull the filter out, wet it, and put it all back together. It’s also larger and more energy-efficient than our other picks. Not only will you have to clean the Venta less often, but the 2-gallon tank means you won’t have to deal with refilling it as frequently, either. The onboard controls are great at preventing over-humidification.
