Should I Recharge My Dehumidifier without Any Expert? 

It was easy to recharge a dehumidifier in older times, but now, as the air pollution increases, it is getting hard to deal with it. So, the units have some dangerous chemicals that might result in a disaster while recharging without an expert. 

We suggest you recharge a dehumidifier by hiring an expert so nothing can go wrong, and you get your unit back with its highly efficient operation. 

The best Time to Recharge a Dehumidifier?

If you recharge the dehumidifier more frequently, it might lose its potential to efficiently remove moisture from the air. It would help if you recharged it only when it is needed. Following are a few signs that can tell you when it needs recharging. 

  1. No change in humidity level

The main purpose of the dehumidifier is to keep the humidity level of your room at an optimum level. You should check the humidity level of your room and then observe whether the operation of the dehumidifier is helping it change its level.

If it is not changing the level, you should first check the fans and filters. If you see no other issue, then it is time to recharge it. 

  1. Moist air 

When the dehumidifier operates, it exhausts dry air because the moisture is condensed, and water is squeezed into the water tank. When you need to know the time for recharging, you can check the exhausting air; if it is not dry and you feel moist, then it is the time to recharge the unit. 

  1. Water tank  

If you use the manual drainage option in dehumidifying, the water tank is another help to check the recharging need. If the machine is running, but the tank is not receiving the expected water amount, you should recharge it immediately to keep the operation running. 

  1. Indicator 

The control panel can tell you about the recharging need in some smart units very easily. It has a light that turns red when recharging is needed. It is a light indicator and alerts the user without any great effort. So, buying an updated smart system is always a better choice.

Which Dehumidifier Needs Recharging?

The dehumidifiers with a coolant or a refrigerator need recharging. Most modern-day units have them, but you should confirm it from an expert. The two main types that need it are desiccants and refrigerator dehumidifiers. 

How to Recharge a Desiccant Dehumidifier? 

The desiccant dehumidifier contains silica gels. They absorb the moisture and change their color. When they completely change their color, the users need to recharge the unit by simply plugging it into an electrical socket.   

Types of Coolants

Following are the types of coolants that are found in rechargeable dehumidifiers. 

  1. Freon / R-22

This one is used in an old dehumidifier designed before 1995. Even now, some of the units use them. They are rare, and it is hard to find them in the market. 

  1. Puron / R-410A

It is the replacement of the previous one. It is environmentally friendly, and almost every modern-day dehumidifier has it. You can use this new coolant with an old unit because the methane gas requires more pressure, and you might end up in a disastrous situation. 

  1. Silica gel beads

This is used in desiccant dehumidifiers, and they are beads that change their color when they absorb moisture. They produce more heat than other units, but they are cost-friendly and easy to maintain.  

Safety Measure You Must Take while Recharging Dehumidifier 

Safety Measure You Must Take while Recharging Dehumidifier 

Recharging is a process that contains chemicals and other highly pressurized contents. You should follow these few safety measures so you can be saved from hazardous situations. 

  1. Keep it out of reach from children

If there are children at your home, you should take precautionary measures. Both the dehumidifier and the filler must be kept out of their reach as they might think it is a toy and fall into a damaging situation. 

Although some of the units have a child lock, recharging doesn’t come with any such preventions, and the users must take care of it. 

  1. Choose an area with good ventilation 

As told earlier, the recharging contents have chemicals, and you should avoid breathing in these fumes because they can cause any infection. You should do the process in a place where good ventilation and fresh air can pass through it. So, the harmful fumes cannot affect your breathing. 

  1. Stand the unit upright

You must stand the unit upright so the recharging can be done effectively. Additionally, plug in the recharging socket from the top, so you avoid any fire breakout.  

  1. Heat resistance 

When you recharge the dehumidifier, it heats up. To avoid any harmful consequences, you should do it on a surface resistant to it. 

Additionally, make sure that you don’t cover the unit as it can cause more heat. Open it as much as possible and let the air travel through it while doing the process.

  1. Call an expert 

This is both a safety and essentiality to call an expert for doing the process. Don’t expect that only watching a video can teach you recharging. You would need professional training to deal with the highly pressurized components. 

Conclusion 

A dehumidifier is now more a need than a luxury. It is essential to keep the air quality better for healthy breathing and goodbye to dust and other allergies. Some units need recharging and doing it the right way saves the unit. Otherwise, you may end up wasting your money. 

The best way to recharge is by hiring an expert and following all the instructions and preventive measures. The best time to recharge can be observed by looking at different signs, including humidity level, moist air, water tank levels, and indicator. 

We wish you luck with charging your dehumidifier the right way.
