PureGuardian offers a series of ultrasonic humidifiers. All are durable and easy-to operate units that alleviate cold and allergy symptoms, soothe dry and itchy skin and maintain your home at optimal humidity levels. Our review features the PureGuardian H4610, an ultrasonic humidifier that creates both warm and cool mist, and it can run for up to 120 hours.
On its highest speed, the PureGuardian H4610 air humidifier transforms nearly a gallon and a half of water into mist every 24 hours. This high mist output is ideal for use in medium to large rooms of up to 650 square feet. In smaller rooms, you simply turn the fan speed down. On the lowest speed and humidity output, the unit runs for several days without needing to be refilled. The H4610 comes with both cool and warm mist settings that each provide soothing moisture. The manufacturer recommends the use of only the cool mist settings if there are children in your home, as the warm mist process creates hot water that poses a scalding hazard should the unit be tipped or overturned.
This unit does not come with a built-in demineralization filter. Therefore, if you have hard water in your area, the ultrasonic operation of the H4610 may disperse a fine white dust into the room you are humidifying. Although you do not have to purchase a demineralization filter for this unit to work, these are available and it???s a worthwhile purchase if you have hard water. It will enhance the performance of your humidifier and help prevent dust buildup in your home. Using distilled or purified water can also help.
The PureGuardian H4610 operates almost silently. You can use it in your bedroom without being woken up by the annoying sounds of a tank gurgling or water sputtering. The digital display also includes a soft night light that enables you to make adjustments in the middle of the night without turning on an overhead light. One of the nicest features is a split spray nozzle that sends mist in two directions instead of one. This is ideal if you have two sick children or want to aim the mist into two areas of your home.
There is no humidistat on this model to measure the humidity of the room. This is unusual for a unit of this price, and the omission makes it difficult keep your musical instruments or expensive wood floors at a specific humidity percentage.
The PureGuardian H4610 is a sturdy unit with a tank that is flat at the top. Because the 2-gallon tank can sit flat in your sink, it is easier to refill and less likely to fall over and shatter. The tank???s plastic is infused with patented Silver Clean technology to fight the spread of unwanted bacteria, mold and mildew.
All models in this series come with a three-year warranty. There is a toll-free telephone number and email contact form you can use to contact the company if needed. You can also browse the company???s online FAQs page for additional answers to your questions. A user manual is also available online.
The PureGuardian H4610 is a well-designed and durable humidifier that offers quiet, effective and germ-free mist output. The unit has no humidistat for setting room humidity to a specific percentage, but it does have many other notable features like a split nozzle, antimicrobial features and a long running time.
