A Guardian Air Purifier review can help the reader find the best Guardian technology from several options in the market. For instance, picking the best from the eight Guardian Technologies and evaluating the price and features is easier after having read several reviews in one place.
Guardian Technologies AC5250 receives a good value from Retrevo. The best-selling Guardian Air Purifier, as of 2014, is the Germ Guardian AC4825 with a three-in-one air cleaning system and the best balance between price and performance. Germ Guardian sticks out because of its air purifying technologies. The site also mentions the more costly AC5250PT, AC5000 and AC4850PT as the other top Germ Guardian air purifiers.
