                        Whole House Humidifier Buying Guide

                        Best Whole House Humidifier On The Market

                        For a whole house humidifier, you’ll require a forced-air system. The advantage of such a system is the humidistat included in the system so as to measure and regulate air humidity. However, air filters need to be changed regularly to avoid molds.

                        Since there are a number of things that you may need to consider while purchasing a house humidifier, here is a list of things to make your buying decision easier.

                        Know the weather

                        Humidity is low during winters, and high during summer seasons. Both situations are not ideal for health and therefore, installing a whole house humidifier is an ideal option. Therefore, knowing the local weather is important.

                        The setting of the humidistat is important as higher humidity indoors can lead to the development of molds. It can also create condensation on windows, increase bacterial growth, dust mites, etc. And, if the humidity is lower, it may lead to dry skin issues, irritation on the skin, nose, and sinuses.

                        Know which humidifier to buy

                        There are numerous types of humidifiers intended for various purposes. For domestic uses, a whole house humidifier is sufficient. However, there are portable humidifiers and single room humidifiers too which are cheaper than a whole house system.

                        A whole house humidifier draws the water from a house’s plumbing system to provide moisture in the air inside your home. The expenses for the setup are high but the operating cost is low. In addition, they provide moisture to the whole house as compared to other smaller humidifiers.

                        If you are situated in an extremely dry area, then whole house humidifiers are a great option.


                        Whole house humidifiers are a good investment in the long run. However, their working depends on good installation procedures. Hence, if you are installing a whole house humidifier for the first time, hire an HVAC expert.

                        An HVAC expert or technician will be able to point out weak spots and carry out proper installation remedies. A small touch of care goes a long way in preserving the quality of air you breathe.


                        Humidifiers are electrical devices and therefore, make noise while in operation. However, ultrasonic humidifiers are silent and do not make much noise. Ideal for homes and offices, ultrasonic humidifiers are easy to handle.

                        However, ultrasonic humidifiers are more expensive than the regular humidifiers. Whole house humidifiers are usually loud and therefore, should have proper damping and air filters to reduce noise.

                        Check for warranty

                        Almost all humidifiers come with a warranty. Since the appliance works all around the year, it is better to look for extended warranties. This would help to cover up any unforeseen expenses if any.


                        A good humidifier maintains a healthy humidity level in your home safeguarding your health. It also enhances indoor comfort, protects the walls and floor of a house and keeps dry air at bay.

                        So today, we pick the Aprilaire 700 Whole House Fan Powered Humidifier as the best whole house humidifier in the market. Given its size with respect to its working capacity, the small unit is powerful as compared to other units mentioned in here.

                        Apart from this, the unit proves to be a good investment and has a long life too. The compact design is also convenient for storage.

                        Hope we addressed all the important points regarding a good whole house humidifier and helped to make your buying process easy with these product comparisons.
