Centralised AC & Humidified
Humidifiers and dehumidifiers have control specific to their purpose.
For humidifiers the control is called a humidistat. Humidistats use computer technology to measure the outdoor temperature and indoor humidity and continually adjust the indoor humidity of your home to an optimum level. They can mount to the wall and looks similar to a programmable thermostat.
On the flip side, whole house dehumidifiers and many portable units are run by controls called dehumidistats. Within air conditioning systems, these can be used to help control mildew formation.
Features and brand considerations : –
There are many brands of dehumidifier and humidifier equipment available, both in stores and through your heating and air conditioning contractor. Our overall opinion about brand is this: compatibility with your indoor air environment, features, service, and perhaps manufacturer’s warranties are important factors. Especially, in a central system, the service you get from your provider will make a big difference. Within that context, brand could be a deciding factor if all or most of the other factors are equal.
For dehumidifiers :-
For dehumidifiers, the primary feature to compare is the dehumidifying capacity, which is measured in pints per day. A small-capacity unit would have a rating of about 25 pints daily, while a large capacity one would be rated at 50+ pints. A unit with higher capacity works quicker and more efficiently than a smaller one.
Plus, it would work in a wider range of humidity levels or room sizes.
After dehumidifying capacity, the most important features are ease of water removal, controls, and warranty.
Select a model with an easy-to-empty water container, preferably with handles and a lid to prevent spills. A useful alternative feature that saves you from having to manually empty the container is a drain hose or fitting for one. With a hose you could route the trapped water to a floor drain or perhaps to under sink plumbing. Other desirable features include easy to read and understand controls, especially digital electronic ones.
