What scent kicks you first when you walk in through your door? While most of us anticipate sweet smells from the kitchen, but we, unfortunately, get hit with musty smells of mildew, mould, and dust. High humidity makes our home and office less attractive, and mould is probably the cause of recurrent asthma attacks. Keystone dehumidifier KSTAD70B is one of the best solutions. If your pet’s allergies are getting worse and there are black growths in the bathroom, basement and the kitchen, then you will go for a dehumidifier. You know that you cannot ignore the dampness and the sneezing even after upping that antihistamine dose!

Moreover, there will be no fresh air to breathe if you don’t have a dehumidifier installed in your home. Hence, we are here to give a solution to your problem; i.e., Keystone KSTAD70B, which is the best dehumidifier for your home. So, let’s have a look!!

Keystone Dehumidifier KSTAD70B Review 2020

Within 24 hours, this Keystone KSTAD70B dehumidifier can remove up to 70 pints of moisture from the air. This best dehumidifier can dehumidify up to 3,800 sq ft, which is more compared to others. It makes the KSTAD70B dehumidifier the right choice if you are looking for the best one for your entire home. This 70-pint dehumidifier also works well in a workshop, basement or garage. 

The water-collection of this Keystone dehumidifier reservoir only holds 10.4 pints. While the water-collection reservoir is smaller, the Keystone allows for continual water drainage. That means you can bypass discharging the bucket altogether. You can attach a garden hose to the drain spout and arrange the hose, so it empties into a nearby floor drain.

This dehumidifier comes with a standard two-speed fan. On the low setting, the dehumidifier is quiet, although, in that setting, it takes longer to remove humidity. The higher setting is noisier but not overly so compared to other dehumidifiers we reviewed that were much noisier. The sound level of this Keystone KSTAD70B measures 53.3 decibels (on the high setting). It is comparable to the sound a dishwasher emits. The low fan setting of this best rated dehumidifier is even quieter. The Keystone KSYAD70B 70 Pint dehumidifier features a built-in settings memory.

There is also a Clean Filter alert in this quiet dehumidifier. Hence you can maintain the clean air quality in your home. This Keystone small dehumidifier comes with automatic features that let the machine regulate humidity levels even when you are not at the house. Moreover, the Auto restart turns the dehumidifier back on after a power outage. It remembers the humidistat’s programmed levels, so you don’t have to readjust the control settings when the power comes back on.

Keystone KSTAD70B dehumidifier FEATURES

  • Full-bucket alert with an automatic shut-off feature
  • Continuous draining option
  • Easy-To-Clean Filter
  • Removable, easy-cleaning dust filter
  • Electronic Controls with LED Display
  • 24-hour timer

While going through this best Keystone Dehumidifier KSTAD70B review, you can find that the delicate feature of it is its drainage system. You will find that this unit consists of a hose for gravity drainage or comes with an attachment to link to the standard garden hose. It requires you to plug in an adapter to make use of the gravity drainage option. For this, you need to utilize the screwdriver and the set of screws for the purpose. That proves out to be a minor negative point while using this unit.

The Keystone dehumidifier is one of the best options for the basement. This one is the most energy-efficient if we look into the range of 70-pint dehumidifiers. Although the Keystone KSTAD70B comes with a rating of 720 watts, it draws only 590 watts. Only in cases of severe humidity problem, the Keystone will operate at high power. If you use this Keystone 70-pint dehumidifier for mild tasks, then this can prove out to be an excellent option in terms of energy efficiency. You can look at other dehumidifier ratings when it comes to energy efficiency; you will be surprised to know that this KSTAD70B Keystone stands out from the rest.

Ease of use is something that you would be glad to know through this Keystone 70 pint dehumidifier review. This Keystone comes with a basic and small LED display. It is quite simple and easy to use with fewer hassles involved. Entering the settings into this Keystone KSTAD70B is easy and simple. This dehumidifier features a slide-out filter which helps in easy cleaning and removal. However, this is a positive point, although you would not be cleaning the filter often. Emptying the tank of this Keystone 70 Pint dehumidifier KSTAD70B often can be an issue because of the small tank size. However, this problem would not persist if you use the gravity drainage feature. Above all, the system is easy to use and also less expensive.

When we look at another dehumidifier sale, the Keystone KSTAD70B dehumidifier comes with a one year warranty on the unit. Two to five year warranty is offered on the sealed system that includes the compressor and the condenser. Keystone is a Chinese product. The warranty is yet to be respected as this best dehumidifier has been on the market for only a couple of years.

Do you have multiple rooms to “dehumidify”? If yes, this Keystone energy star 70 pt. dehumidifier is the best choice as it comes with wheels for easy transportation. Another feature you like about this best rated dehumidifier is the auto-restart option that saves the settings in case of a power outage. Moreover, if you are among the category of users who worry about emptying the water tray every time it gets full, don’t despair as this dehumidifier allows for continuous drainage.
