How to Use NPET Dm800 Electric Mini Dehumidifier?
To use this product, follow these simple steps:
- Check that the detachable tank is in place and positioned correctly
- Plug the dehumidifier into the outlet
- Toggle the on/off switch from off to on to remove moisture from a humid room
- Empty the water tank when the blue light changes to yellow
- Clean the air intake filter once every two to four weeks
Right out of the box, you will find that no additional accessories are accompanying the NPET Dm800 electric mini dehumidifier except the power brick.
It’s a compact unit with a one-button setup that makes it easy to use. Plug it into the outlet after checking that the tank is in the correct position and it kicks right into dehumidification mode to start removing moisture from the air.
To ensure the system works, use it in a room with a temperature above 59°F and below 80°F. The mini dehumidifier will not work optimally under lower and higher temperatures and may ultimately not work at all.
Similarly, the relative humidity should be between 50% and 80% for the dehumidifier to work effectively. You likely won’t have problems with this as very humid rooms are around 70 to 80% relative humidity.
In such a situation, the NPET Dm800 electric mini dehumidifier should protect your valuables from mold growth, mildew, bacteria, and any other moisture-related damage.
Once it’s turned on, it will alert you with a blue light. The dehumidifier starts extracting excess moisture from the air and condensing the air once it’s powered on.
Over time the condensate (water) accumulates into the detachable water tank. When complete, it alerts you with a yellow light and the dehumidifier shuts off automatically until you empty the tank.
Under ideal operating conditions, the NPET Dm800 mini dehumidifier can rid your indoor air of 9 ounces of moisture in 24 hours. It also has a low sound profile under 32 DB and consumes 0.25 kWh of electricity so that you can run this around the clock without worry.
You can also use this mini dehumidifier in different places, though you should keep its small profile in mind. It won’t remove moisture effectively from a damp basement or a humid open area kitchen. Use it in small spaces for the best results – places like a wardrobe, small offices, bedrooms, mini-libraries, and similar areas.
Opt for whole-home dehumidifiers or standard portable humidifiers with compressors for more effective dehumidification for larger areas, or dehumidifiers with active HEPA filters to better air purification.
How Do Electric Dehumidifiers Work?
Electric dehumidifiers use the same refrigerant cooling principle of air conditioning units but combine this with heating to remove moisture from the air. As a result, humid air between 60% to 100% relative humidity is, in essence, treated to reduce indoor air humidity to 30% to 50% humidity.
To understand this process completely, you need a picture of the components of a modern electric dehumidifier. Its components include:
- A cold evaporator coil
- A hot condenser coil
- A fan
- Compressor with refrigerant gas
- Water tank
Once a dehumidifier is connected to electricity, the compressor propels the fan to draw humid air through the intake grille, passing through the cold evaporator coil. This cold coil condenses the air’s moisture to water, which collects in a tray and drips down into the reservoir water tank.
Now the cold, dry air moves on to the hot condenser coil to bring the cold air back to room temperature and further dry the air. The air, now ready for expulsion from the system, is drawn out by the same fan and released as moisture-free air corresponding to the set humidity levels.
An electric dehumidifier will continue this process until it extracts all moisture present in the air and until the relative humidity level in the room is uniform.
The differences between standard electric dehumidifiers are based on effectiveness, capacity, and other beneficial features.
For example, some electric dehumidifiers use active HEPA filters to improve indoor air quality and remove allergens, pollutants, odors, microbes, and other particulate matter.
Some incorporate innovative technology like Wi-Fi that allows remote monitoring and control away from home and Ionization systems break down pollution in the air. Others ship with pumps that automatically drain water from the system or have several different fan and laundry modes that add more functionality to the mix.
Others, like the NPET Dm800 electric dehumidifiers, are compact and portable for use in places not larger than 100 to 300 square feet in size.
When purchasing electric dehumidifiers, consider your preferences and the additional functionality you will need in order to make the best choice. Also, be mindful of the amount of moisture it can extract from air under 24 hours as this is also an important feature.
Do Dehumidifiers Need to be Plugged In?
Like all electronic appliances, dehumidifiers should only remain plugged in when in use and should be stored away whenever you are away from home for an extended period of time. It will help you save electricity and increase your dehumidifier’s life span and effectiveness.
Dehumidifiers help remove moisture from your home. They keep mold at bay, remove dust from your home, and even help with allergies and respiratory problems. Still, it is not recommended to keep it plugged in all year.
Unplug your dehumidifier when away and keep it unplugged and stored during winter. Humidity levels drop in the colder months, and things get much dryer, so you won’t need the assistance of a dehumidifier to dry out the air.
From reading this guide, you may have also noticed that the NPET Dm800 mini dehumidifier does not work effectively below 59°F, and during winter, temperatures drop even lower than that. So it is not adequate to use dehumidifiers at low temperatures.
All other dehumidifiers follow this same operating parameter. If you run a dehumidifier when it’s cold, you risk drawing in cold, dry air that will only get colder when it hits the cold evaporator coil and it may possibly freeze the unit up.
Do Mini Dehumidifiers Really Work?
Electric dehumidifiers use the above process to remove excess moisture from your home. However, mini dehumidifiers use a slightly different method to reduce humidity. They use smaller components and a Peltier module with two heat sinks to achieve dehumidification.
Smaller components reduce mini dehumidifiers’ effectiveness but don’t take from their usefulness in small areas or crawl spaces.
A large dehumidifier will be more effective than a mini dehumidifier but a mini dehumidifier is more effective than passive dehumidifiers. So yes, they work.
How Do Mini Dehumidifiers Work?
Mini dehumidifiers remove excess moisture from indoor air by passing humid air through a Peltier module sandwiched between two heat sinks.
The cold heat sink condenses water molecules in the moist air and the hot heat sink increases the temperature of cold, dry air to room temperature before the fan blows the same stream of air back into your home.
Mini dehumidifiers use the thermo-electric effect in a Peltier module to dehumidify moist air and use smaller components with basic features. The process is different from standard electric dehumidifiers that use compressors with evaporators and condenser coils. It’s also separate from desiccant type dehumidifiers.
The Peltier module present in mini dehumidifiers creates a warming and cooling effect on each side when connected to electricity.
The module establishes a temperature difference that allows one side to absorb heat and the other to radiate heat. Two heatsinks are sandwiched on each of these sides. The cold one faces the air intake grille and the hot one faces the air outlet grille.
Here is a step-by-step guide to how a mini dehumidifier works:
- When you plug in your mini dehumidifier, the electric fan draws in the air with considerable moisture content into the intake grille.
- The air comes into contact with the cold heat sink, the heat from the air is absorbed, and the cold temperature condenses the water molecules in the air to condensate, leaving cold, dry air.
- The condensate is collected on the cold metal plates of the heat sink and drips down into the water tank.
- The air continues moving with the help of the fan to the other side of the Peltier module until it comes into contact with the hot heat sink. The hot metal plate radiates heat that raises the cold, dry air temperature back to room temperature.
- The fan then blows the dry air into your home at room temperature.
- As the water level rises, the float contained within rises as well, and when full, it sends a signal that shuts the dehumidifier off to avoid overflowing.
The NPET Dm800 electric mini dehumidifier uses the process outlined here, similar to other mini dehumidifiers, but some passive dehumidifiers (also called mini dehumidifiers) use an absorption method to remove moisture from indoor air.
Frequently Asked Questions
How Good is the Peltier Dehumidifier?
Although Peltier dehumidifiers are very durable and have a long lifespan, they are not as effective as compressor-based dehumidifiers. Firstly, because they are used for mini dehumidifiers, the Peltier modules are smaller and are made of lower quality materials to be cheaper. As such, they are not very effective. Secondly, the fans are susceptible to breaking down. On the other hand, Peltier dehumidifiers are very quiet and can operate for longer extended periods while consuming little electricity. These types of dehumidifiers are best for small spaces and crawl areas.
Can You Drain with a Hose Instead of the Water Tank?
No, you cannot drain with a hose. You can only drain water using the water tank. You must manually empty the tank to keep using the dehumidifier when it is full. Mini dehumidifiers do not feature alternative drain options because of their small size and intended use space.
How Loud Are Mini Dehumidifiers?
Mini dehumidifiers are quiet when in use. This is because of their mechanism of operation. Peltier modules do not contain many moving parts, except the fan, which is the only component that contributes to the noise profile. Still, the sound most mini dehumidifiers make is less than 40 DB. Some models are even as low as 30 DB.
Will a Dehumidifier Help with Mold?
All Dehumidifiers are built to help extract excess moisture from humid air, which helps to prevent mold growth, mildew, and to protect your home from damage from moisture. Dehumidifiers with active filters also help with respiratory problems by removing allergens, dust, particulate matter, and bacteria from the air.
The NPET Dm800 electric mini dehumidifier is an essential machine that is ideal for removing moisture from small areas, offices, mini-libraries, and crawls spaces.
