Product Review

The pro breeze PB-04-US dehumidifier is one of the best and most popular rechargeable cordless dehumidifiers among consumers. It is a great option for people who do not want an electric dehumidifier. This dehumidifier is a compact and portable device that can be carried out easily and used in different spaces in your home.

The dehumidifier has a modern white design that makes it easy to blend with the décor in your home. It will not occupy much space in your home or interfere with the aesthetics of your space.

It is a great option for small spaces like wardrobes or closets, cars, laundry rooms, bedrooms, medium-sized toolboxes, small bathrooms, tents during camping, the area under the sink, cabinets, and any other relatively small space in your home.

This dehumidifier is easy to use. You only need to position it upright and then turn it on for it to work. After that, all you will need to do is monitor the indicator for color changes which will help you know if you need to recharge the dehumidifier.

The pro breeze PB-04-US dehumidifier is a rechargeable dehumidifier that uses silica gel technology for its operations. The silica gel beads used in the dehumidifier use the same network mechanism of capillary condensation to trap moisture.

The moisture absorbed by the silica gel beads at the upper-most part of the dehumidifier is transported to the lower beads using a capillary network technique.

The dehumidifier has an indicator that will help you know when the silica gel beads are saturated.

After recharging the dehumidifier, the indicator will also alert you so that you can unplug the dehumidifier from the electrical outlet and continue using it. Recharging the dehumidifier dehydrates the silica gel beads, which enables them to absorb more humidity from the air.

The dehumidifiers can be used for 20 to 30 days consecutively before the silica gel beads become saturated. After the silica gel beads are saturated, you will need to recharge the dehumidifier for approximately 10 hours for the silica gel beads to dry properly.

Charging the dehumidifier for short durations than the recommended time will mean that you will need to recharge the dehumidifier again after a few days.

You should also avoid over-charging the dehumidifier after the silica gel beads are saturated as that will damage your dehumidifier over time and reduce its life span. Ensure that you check the indicator to know when the dehumidifier is fully charged.

The section where the silica gel beads have been placed cannot be easily dismantled by children or pets. The safety features considered in the design of the dehumidifier also reduce the risks of silica gel spillage, which makes it a safe option for travelling or for using around children or pets.

This dehumidifier is 100% cordless, which means that when you are using it you will not have to worry about tripping over the cord. It also has an indicator that shows you that the dehumidifier has been turned on.

Are pro breeze dehumidifiers any good?

Based on our review of the pro breeze PB-04-US dehumidifier among other pro breeze dehumidifiers, we are certain that pro breeze dehumidifiers are good and reliable dehumidifiers.

This dehumidifier will effectively reduce moisture in your home or any other space where you might wish to use the dehumidifier. Check the capacity of the dehumidifier before purchase to ensure that you get a dehumidifier that will be suitable for your space.

Why has my dehumidifier stopped working?

If your rechargeable dehumidifier stops working, check the indicator to ensure that the silica gel beads are not saturated as they will not be able to absorb more moisture from the air if they are saturated.

How do rechargeable dehumidifiers work?

Most rechargeable dehumidifiers use silica gel beads technology. The silica gel beads trap humidity in the form of moisture from the air until they are saturated. The silica gel beads are dehydrated during the recharging process to help them draw more water from the air.

Is there such a thing as a battery-powered dehumidifier?

While the pro breeze PB-04-US dehumidifier is not a battery-powered dehumidifier as it uses silica gel technology, there are several battery-powered dehumidifiers on the market.

Battery-powered dehumidifiers like the airlux battery-powered cordless dehumidifier use the battery in the same manner that an electric dehumidifier would use electricity to draw moisture from the air.
