A beautiful, sleek, yet highly functional air purifier with dual air intake. Gocheer GH-Monster Smart air purifier is a tall air cleaning machine with a bit of weight on it. The 15.9 x 31.9 x 14.8 inches dimension and 34.9 pounds weight will take out some presence in your living room space. Suitable for room-to-room purifying thanks to its integrated 360 degrees castor wheels and universal pulley. The side air inlet panel are removable and can be done with little effort. Right at the front, you’ll have a vertical bright LED light that illuminates when the air purifier is turned on. A nice touch to differentiate from other air purifiers model in the market.

A bliss to use even for first-timer. Gocheer GH-Monster Smart air purifier has all the features you would expect from a premium device. The beautiful touch panel comes with 4 adjustable fan speeds that you can set a balance between performance and noise output. The built-in particles sensor enables the air smart indicator, sleep mode, and auto mode. Auto mode is our favorite bunch that only uses high speed when the concentration level of indoor airborne pollutants has increased. There are also other useful features like 4 preset timers that can be set to shut down the machine, a child lock to prevent children from meddling with the controls, a filter reset indicator, and a lighting dimmer button that dims down all indicator lights.

Unique in Gocheer GH-Monster, there is a smart app control that allows you to remotely monitor and control the air quality at the comfort of your bed. Just download the Connect app from iTunes or Google Play and you can start using the Wi-Fi remote control access on your smartphone or tablet.

Gocheer GH-Monster comes with every passive feature of a premium model. It is electrical safe in accordance with ETL/ UL standards. It is also California Air Resources Board (CARB) approved for ozone-safe. The allergen remover performance is certified asthma & allergy-friendly by the Asthma and Allergy Foundation of America.

You can also manually set the fan speed to low and dim the lights before you head to bed. Power consumption is good with almost 35% more energy-efficient than the same segment air purifiers.

^ Replacement filters/ estimated cost
Gocheer GH-Monster Smart air purifier has a "monstrous" price of 500 dollars which is not meant for everyone. The high price tag is mainly contributed by the outstanding air cleaning coverage and abundance of features. The high filter cost is perhaps the biggest killing blow where you have to pay up to 260 dollars annually for maintenance. That said, Gocheer GH-Monster could be the only air purifier you need instead of having multiple units at home.
While Gocheer GH-Monster Smart 4-in-1 air purifier has good availability online, not many places will carry it given its low volume sales. The best place to get one is still on Amazon as it comes with seasonal offers, bundled deals, free shipping, installment plans, and a hassle-free shopping experience. The official Gocheer website is doable as well with standard free shipping, a 30-days return policy, and lifetime customer support.
