Why Central Air Conditioning Alone Cannot Hold Target Humidity
Central air conditioning removes moisture as a byproduct of cooling, but only while the cooling cycle is active. In mild weather, when the AC cycles infrequently or runs short cycles, the system cannot stay on long enough to extract the moisture load — humidity climbs even with target temperature held. Central air dehumidifiers solve this by running independently of the cooling cycle, dehumidifying continuously based on humidity setpoint rather than temperature. Integrated into the central HVAC ductwork, they share the supply distribution that conditions the entire home, delivering uniform humidity control across every room without portable units in occupied spaces.
Sizing Central Air Dehumidifiers for Residential Application
Central air dehumidifier sizing follows total conditioned square footage, climate zone moisture load, and HVAC system CFM. The Ebac CD60 (60 PPD) and CD85 (75 PPD) cover small residential homes 1,200–1,800 sq ft in moderate-humidity climate zones. The CD100 and CD100E (90–97 PPD) handle typical 1,800–3,000 sq ft homes including humid southern US climates where the moisture load is consistently higher. The K100E (97 PPD WiFi-enabled) adds remote humidity monitoring through a smartphone app — useful for second homes, vacation properties, and homeowners who travel and want humidity verification while away. The CD200 (138 PPD, 664 CFM) and AD850E (95 PPD) cover larger homes 3,000+ sq ft, multi-zone HVAC systems, and homes with attached dehumidified spaces (basement, crawl space, garage).

Integration with Existing Central HVAC Systems
Central air dehumidifier integration uses one of two install paths. Side-mount installation places the dehumidifier in parallel with the air handler's return duct, drawing return air through the dehumidifier, dehumidifying, and returning to the air handler for distribution. Stand-alone with shared distribution mounts the dehumidifier separately from the HVAC chassis but uses the same supply ductwork — useful when the air handler location does not have clearance for side-mount equipment. Either configuration requires HVAC contractor installation including duct modifications, drain routing, electrical connection, and humidistat integration with the existing thermostat or a dedicated humidity controller. Confirm warranty coverage with the HVAC professional — some manufacturers require professional installation for the warranty to remain valid.

This vacuum is very light and powerful
Gets the job done without hassle. This vacuum is powerful and reliable for everyday cleaning. Definitely recommend it.
we have three cats, and this purifier has done wonders in removing pet odors and dander
Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our home’s central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
this bedroom purifier has transformed my sleep quality. the air is so much fresher and cleaner worth every penny
very customer friendly and professional design.
perfect for maneuvering in tight areas the HEPA filter is a huge bonus
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
This vacuum has exceeded my expectations. It's super powerful and handles daily cleaning with ease. I recommend it to everyone.
really effective in sweeping up all kinds of debris from our warehouse floor
works wonders on tough carpet stains. it's compact and easy to use for upholstery cleaning too
