Sharper Image Air Purifier Detailed Reviews hybrid gpgermicidal small



Model: Hybrid GP Germicidal
Sharper Image Air Purifier
Last Reviewed: 01-09-2008
Rating Score: 64/100 points

Summary: Sharper Image makes neat looking "stuff". The quality keeps getting better and better; however, here we have a purifier with low maintenance costs and low energy usage, but not enough real cleaning power for the price. Sharper Image does run specials including the second purifier at half price, but has only a 1-year warranty. If I were to buy this purifier, I would definitely buy two to save money and purchase the 5-year extended warranty from previous SI experience.

Basic Specifications: The Hybrid GP Germicidal is designed for larger rooms. This purifier is mostly passive technology as the air must pass through the purifier to be cleaned. The technology includes a cleanable pre filter and an electrostatic precipitator. The cleaning process does create some oxidizing plasma and ozone which Sharper Image claims stays inside the unit. Whether it does or doesn't, it does add extra cleaning power and will reduce odors and gases. The purifier has 4 speeds plus a "boost" setting. No replaceable filters or parts. A standard 1-year warranty is included. Has some "plastic" smells out of the box - outgassing.

Clean Air Delivery Rate (CADR) rating from The Association of Home Appliance Manufactures (AHAM) Smoke 141 / Dust 175 / Pollen 192 *** Special Note *** Sharper Image Uses this measure for this purifier, but has not actually submitted to the AHAM. This makes the reading less meaningful as a comparison to other CADR rated units.

Summary: Sharper Image makes neat looking "stuff". The quality keeps getting better and better; however, here we have a purifier with low maintenance costs and low energy usage, but not enough real cleaning power for the price. The silent feature is nice, but cuts down on actual cleaning power unless you have adequate room airflow. Sharper Image does run specials including the second Sharper Image air purifier at half price, but has only a 1-year warranty. If I were to buy this purifier, I would definitely buy two to save money and purchase the 3-year extended warranty from previous SI experience.

Basic Specifications: The GP Silent is designed for larger rooms. This purifier is mostly passive technology as the air must pass through the purifier to be cleaned. The technology includes a UV lamp and an electrostatic precipitator. The cleaning process does create some oxidizing plasma and ozone which Sharper Image claims stays inside the unit. Whether it does or doesn't, it does add some extra cleaning power and will reduce odors and gases. The purifier has 3 speeds plus a "boost" setting.

3) Yearly Operating Costs: 15/15 points - The only consumable cost is the UV-C light at $24.95/year. Calculating electricity usage: 28 watts/1000 X $.0886/kwh x 24 hours/day X 365 days/year = $21.73/year. Total cost $46.68/year. Very Inexpensive to operate.
