The LAD1814 is a  “whole house air filtration system”. The LAD has a capacity of 400 to 1400 cfm.  This unit fits in-duct, normally next to the furnace blower. The LAD1814 joins to duct work that has an opening of roughly 18″ x 14″. The system filter is a electrostatic cell with over 13,000 square inches of filtering surface. This electrostatic filter is powered by a power pack that puts out 8K DC Volts at low amperage. This low amperage results in very low ozone emission as a result of the purification process.  A Canadian study found that electrostatic whole house air filtration systems provided the best improvement in indoor air quality with the 2nd lowest cost of maintenance.

Economical, Safe Long Term Service

The LAD1814 whole house air filtration system uses just 42 watts of electricity to clean the air in your entire home. If you ran the air purifier 24 hours a day 365 days a year it would cost you about$45.00 for the entire year. The free flow design allows our furnace and HVAC fan to run easier using less electricity as well. The LAD1814 has several safety feature like a grounding strap and  safety micro switch. The LAD1814 emits about .0048 ppm of ozone which is below the level accepted by the State of California. All LakeAir models have a history of long service.
