Daisy advantage over ducted systems: 2 hour, no cleanup, no restoration installation. Avoids moisture/mold issues from delivering hot, humid air condensing onto chilled drywall surfaces in AC closets. Excellent, automatic ventilation rate control. Portable to fit prepared ports.

Daisy Ductless (Smart)

Daisy installs from indoors through an exterior wall on any floor, low or high rise. Integral MERV 14-15 filter (service from indoors)  and ECM impeller fit within its 9.25″ length completely within exterior wall flush with drywall indoors, and outdoor surface. Smart controls include carbon dioxide, VOCs, temperature, humidity dynamic control 0-70 cfm as determined by smart controller measurements and microprocessor calculations. Powered by 12vdc 2a wall adaptor. Blue Boar creates perfectly aligned ports through exterior wall. VIDEO

Lotus Ducted (Smart)

Exterior mount requires exterior access for installation/service. Incorporates Honeywell HRF-11 HEPA filter. Variable speed 0-160 cfm. Smart controls include carbon dioxide, VOCs, temperature, humidity dynamic control 0-70 cfm as determined by smart controller. Powered by 12vdc 6a wall adaptor

Red Zephyr Ducted (Smart)

Carnation Ductless (Presently Not Smart)

Presently manually speed controllable 0-60 cfm


REX Ductless: 

ASAPDB – A unique design awaiting patent protection. The REX, a very quick and precise installation, is able to extract radon from “radon reservoirs” that exist in many buildings in south Florida and perhaps in many other locations worldwide. The REX has demonstrated effectiveness in radon reduction while consuming only 3-4 watts of energy. The REX will not increase indoor humidity or loads on the air conditioner. REX will not be effective in some buildings with certain construction HVAC designs/defects. It is believed that should architects learn more about ASAPDB functionality, they will seek to incorporate it into nearly all new designs. In hot, humid climates initial indications are that REX radon management may render ERVs, dehumidifying ventilators, supplementary dehumidifiers, HRVs, and massive fresh air systems unnecessary. Instead one can rely on micro pressure management and eliminate unintentional internal/interstitial airflows. Thank you Lawrence Berkeley National Laboratory, Building Science Corporation, Indoor Air Quality Association, Florida Solar Energy Center, International Society of Indoor Air Quality and Climate, and the Energy Conservatory for providing the theoretical knowledge, skills and extensive, sophisticated instrumentation that revealed factors not earlier well-understood.
