Germ Guardian Reviews and Company Overview

Guardian Technologies creates a wide variety of small-appliances. And, each of thier appliance categories focuses on improving air. To help add a little moisture to the air they offer ultrasonic humidifiers. And to spruce up the smell Guardian has a line of aromatherapy products. But, thier core focus is on home air purifiers. Germ guardian reviews typically focus on the ubiquitous AC4825 model but we think their entire purifier line deserves consideration.

Their full range of air purifiers incorporates several designs and filter technologies. But, the thing we really like is that they provide HEPA filtration and activated carbon at a very affordable price point. Which makes Germ Guardian air purifiers are a great pick when it comes to in-home machines.

With solid filtration systems and low prices, they are an incredible value. If you’re shopping for a purifier to place in a small to mid sized room we think you’ll be pleased with at least one of the following options.
