Things to Look for in Buying the Most Efficient Whole House Dehumidifiers

whole house dehumidifier reviews

With the vast number of features available in today’s dehumidifiers, having a standard set of criteria can help a great deal in choosing the right one for your household needs. When buying a dehumidifier, the general rule is to look at its capacity to hold water, energy efficiency, price range, and noise output.

According to the U.S Department of Energy, the two most important standards for the best dehumidifier nowadays are the capacity and the energy efficiency (Energy Star certificate)

Energy Efficiency

Believe it or not, many dehumidifiers nowadays consume so much power to the point that it can singlehandedly double your electric bills. Make sure to check the system’s EPA-issued Energy Star certification, which allows you to save up to $200 monthly in electricity bills.

  • Expert Tip: One of the highest rated in terms of energy efficiency is Ultra-Aire XT 105H, which has water removal capacity of 105 pints per day. However, the Ultra-Aire XT 105H was discontinued for a few years so the Aprilaire E100 Pro may be the best choice in 2024


Now, dehumidifiers also come in various sizes and capacity to hold water – a decision which can be based on the size of your house. Non-ducted dehumidifiers can usually handle small to mid-sized houses or apartments while ducted air cooling machines that can hold up to 100+ pints per day can cover larger areas.

  • Expert Tip: For condo-type households of up to a 500 square feet, a non-ducted or a portable dehumidifier with 40-45 pints of water removal capacity is just about enough to cover your needs. Other spaces such as a pool house or a basement may need specially designed dehumidifiers with higher water removal capacities.

Price Range

Anyone looking to purchase household appliances is almost always interested in having the best value for their money. Check the price tag first.

  • Expert Tip: Rethink your calculation whenever you’re tempted to buy the cheapest brand. Perhaps spending a little more can actually save you a great deal better in the long-term in terms of electricity consumption.

Noise Output

Let’s face it, some dehumidifiers tend to be too noisy as it produces an annoyingly buzzing sound in the process of evaporating water into air. With active dehumidifiers open in most parts of the day, a buzzing sound can be unpleasant to the ears.

Now that you have an idea of what to look for in the best dehumidifiers in the market, we took the liberty of listing down the top 5 best whole house dehumidifiers based on the criteria we have set above. While these products are rated from 1 to 5, the best product for you will still depend on your needs.

Abestorm Crawl Space Dehumidifier review

The Abestorm 120 Pint Dehumidifier is a heavy-duty commercial-grade machine that is both sturdy and transportable. Its utilitarian design is complemented by a strong and projection-free case that makes it easy to move around, making it suitable for both temporary and permanent installations.

Upon unboxing and first use, the dehumidifier proved to be relatively quiet, with fan noise comparable to that of a window air conditioner and a nearly inaudible compressor. Testing the machine, the dehumidifier was able to reduce the relative humidity from 51% to 43% in just an hour, and cycled at reasonable intervals as local humidity returned to ambient levels.

However, while the Abestorm 120 Pint Dehumidifier may be a solid machine, there are some disadvantages that potential customers should also consider. Firstly, the drainage system needs to be checked carefully to avoid blocking the flow of condensate and potentially flooding the unit, an issue mentioned in the instructions. Secondly, some customers have expressed concerns over the warranty terms, which exclude consumables such as "switches" and "valves", which could affect a user's ability to self-service and potentially void the warranty if attempted.

In summary, the Abestorm 120 Pint Dehumidifier is a solidly built and effective machine that is suitable for whole house use. Its transportable design and quiet operation make it ideal for both temporary and permanent installations, and it is capable of reducing humidity levels quickly and efficiently.

Tell-tale Signs You Need to Buy the Best Whole Home Dehumidifier

Whether you live in an apartment building, a condominium, or a suburban paradise, humidity can still get the best of us. From molds, mildew, dust mites, poor ventilation and unwanted smells, here are some tell-tale signs that tell you when you need to buy a dehumidifier:

  • Mold spores – Look out for small black spots that usually develop in highly humid areas such as your bathroom, laundry room or basement. These small black spots are most likely mold spores that can easily be eliminated with a high quality dehumidifier.
  • Unpleasant smells – High humidity areas are the perfect breeding grounds for must and mildew. These fungal growth spores are usually a thin whitish coating in appearance and can cause unpleasant odors.
  • Water stains – Unwanted water stains usually appear on wooden walls and ceilings, especially in humid areas. Without a dehumidifier to control humidity levels, these water stains can easily erode wooden panels in your household.
  • Poor ventilation – The best tell-tale sign that you need to buy a dehumidifier right now is when your house or apartment has poor or no ventilation at all. Having a dehumidifier allows air to flow smoothly while controlling humidity levels which can cause harm in the long-term especially for children.
  • Water condenses on windows – Another sign that your house needs humidity control is when you notice water droplets condensing on your window panes. When water condensation appears, it’s most likely that your house is near to inhospitable due to high humidity levels.

People Also Ask

How does whole house dehumidifier work?

A whole house dehumidifier is designed to manage humidity levels across your entire home and works in conjunction with your existing heating and cooling system. It functions by drawing in air from your living area, extracting its moisture, and then circulating this drier air back into your home.

This operation involves a fan, a compressor, and coils. The humid air is guided over the cool coils where the moisture condenses and gets collected. The now dehumidified air is reheated to room temperature before being distributed back into your living area via the HVAC system.

How to install whole house dehumidifier?

The installation of a whole-house dehumidifier involves several crucial steps such as:

  1. Attaching a flexible return-air duct to the port on one end of the dehumidifier
  2. Fastening this duct to roof framing with plastic straps
  3. Creating an exclusive return duct for the dehumidifier
  4. Linking up the dehumidifier to the HVAC supply plenum of your home for reintroducing dry air into the system.

It's vital that you install this device correctly for it to work optimally and efficiently. For comprehensive installation guidelines, you should refer to instructions provided by manufacturers or get in touch with an expert.

Can I install a whole house dehumidifier without ducts?

While standard installation of a whole-house dehumidifier necessitates integration with existing ductwork for distributing dry air throughout your home, there are alternatives if installing ductwork isn't feasible.

Ductless versions are available but may not be as effective at treating all areas of your home.

In such situations, it's advisable to seek professional advice based on specific needs and layout of your home.

How much to install a whole house dehumidifier?

Costs related to installing such devices can vary greatly depending on aspects like your home's size, the type of unit, installation complexity, and local labor rates.

The whole house dehumidifier costs could range from a few hundred dollars for just the unit to several thousand dollars when professional installation is included. To get an accurate quote, it's recommended to consult with a local HVAC expert.

How long do whole house dehumidifiers last?

While it can vary, whole-house dehumidifiers generally last anywhere from 8 to 15 years. Factors influencing this lifespan include the quality of the unit, how well it's maintained, and its usage frequency.

Regular maintenance and correct installation can contribute to extending a dehumidifier's life. Furthermore, manufacturers might offer warranties that provide an idea of anticipated lifespan and cover any potential early issues.

The Final Verdict: Which One is the Most Efficient Whole House Dehumidifier?

The clear winner of this dehumidifier product roundup is the Aprilaire Whole House Dehumidifier. While it falls on the expensive side of the price range, this product is the most energy efficient choice complete with a quiet exhaust fan and a high-performing moisture removal capacity perfect even for larger households.

On the other hand, if you’re looking for a cheaper alternative, the ALORAIR 120 PPD Whole House Dehumidifier provides a more than satisfactory moisture removal capacity. With a relatively lower energy efficient rating compared to Aprilaire, this dehumidifier is more appealing to the pocket and delivers a high quality performance.

Lastly, smaller houses located in condominiums and apartment complexes can avail of the Honeywell and Waykar portable dehumidifiers. Its 70 to 80 pint moisture removal capacity can cover more than enough of your living room all for a cheaper price.

Whether you’re living in a 2,000 square foot mansion or a small bungalow apartment, dehumidifiers have far-reaching benefits for you and your entire family. From lesser risk of allergen exposure to better air ventilation, any of these best whole home dehumidifiers can and will address your needs.
