The unit has excellent heat exchange abilities and superb defrost capabilities that make it reliable and suitable for restoration and remediation tasks. Also, you can choose to replace the filters at the end of the year. Similarly, you can choose to clean the filters during maintenance to improve its efficiency.

For Commercial and Industrial use. We designed with the heavy-duty roto-mold technology, convenient built-in wheels and handles, Ideal for Removing Damp and Moisture from Flood & Restoration, Carpet Cleaning, Basements/Cellars, Laundries, De-Flooding.

How It Works

LGR MAX can be deployed in damp areas to prevent mold and mildew. It is a compact dehumidifier that absorbs a large amount of water from the atmosphere. The unit can be deployed to dry areas saturated with water faster and can continue dehumidifying until structural materials and subfloors are dry. It is one of the dehumidifiers that can be deployed in tight spaces that include hallways, bathrooms, and kitchen. As it goes about its work, you can easily track the dehumidification progress. Even in the event of an outage, the automatic restart will ensure that it continues drying once the supply is restored. Also, the dehumidifier has a built-in pump that will pump condensed water into the drain, toilet or into the sink. 

Where Else Can It Be Used?

LGR MAX can be deployed in areas experiencing leaks and floods. It easily dries spills and will prevent damage to cabinets, walls, and floors. It is quite efficient in evaporating moisture. Other than controlling humidity, the unit can be used to prevent mold from forming. It creates an environment that is difficult for mold growth and mildew survival. If the humidistat can be set at the desired humidity level, it will control moisture and reduce humidity down to that certain percent. 

The basement- if moisture is left to accumulate in the basement, it can escape and cause havoc in the living spaces. Also, when it builds up beyond 50%, it causes mold growth and a musty odor which can be terrible for your health. Installing the LGR MAX will ensure that it pulls moisture out of any dense material so that they remain dry.Generally, more than 70 percent of water damage and restoration professionals use LGR MAX for their day to day remediation tasks. It is reliable, durable and efficient. It has many excellent features such as built-in humidistat, an auto pump system and touchpad controls. Also, the unit can display the outlet and inlet temperatures at a click of a button. Thus, it is the best equipment you can buy for water damage and restoration tasks. All you need to do is to ensure that you close any vents in the crawlspaces to avoid dehumidifying the outside as well. Lastly, ensure that the vapor barrier is well installed.

Fantastic dehu!

The compact design allows me to carry more equipment to a job. The digital screen makes it easy to get all the reading I need quickly. The function and grain depression on this unit out performs my older much larger units. I will definitely be buying more.

This line of mitigation equipment is the best

I just ordered rdered two dehus and put them on two different job sites. They are way better than dri eaz and Phoenix. At the first site the roofers didn t install the valley correct and water slowly leaked inside the studs and drywall for years. After 24 hours of the equipment running, the dehu pulled enough moisture out of the affected material that it was pulling bound moisture out of the walls on day two. There is very few if not any other equipment that can do that. The job was dry in less than 3 days. The photo of the moisture readings proves it. I m going to order more. Plus the wheels make it easy to move around. And the back lid opens up so you can easily store the drain house and wire. Great product.

Great little dehumidifier

This is a great dehumidifier. Very comparable to the more expensive big name brands. We will be adding more to our mitigation inventory.

Portable and Powerful

Machine came as advertised with a couple blemishes strictly from the transportation company, not the manufacturer. After setting up on thr same job next to two other big name units, this one outperformed the other two. Love the handle and wheels. Power cord and drain hose are kept nice and neat in the storage compartment on the top of the unit. Love the machine!

Solid unit, good compact design

I have a restoration company and we have been using this dehumidifier to dry an area that has very limited space. This unit fits and has dried the area well. The temperature readings are pretty accurate as checked with my psychrometer. So far very happy with this purchase.

Quality Dehumidifier

I purchased this LGR dehu to use along with several others I have. Thought I would try these out and save some money. I have a couple more in my fleet and I have not been let down yet. Good company and good products. Its packaged really well and has detailed instructions. The handle and wheels are great for moving around the interior of a house.

Keeps the humidity down, without a lot of noise!

Ordered for our rather large basement, it is doing the work. The humidity dropped from 63% to 40%. Very comfortable, no musty smell. We have a hose connected to it, plug and play. It works very well! It might be a bit too much for a small space.

CADPXS Reply: Dear Marales, Glad to see that it's working well for you.

It's easy to use.

I've been in my apartment for 16 years. Always damp, always smells a bit musty. I was always finding mold here and there. This dehumidifier has changed my life! I ran it nonstop for 2 days in one room, then 2 days in the other. The rest of the place isn't as underground and doesn't have as big of a problem, but still this thing is being put in. Cleaning with a good mold killer and running the dehumidifier for a few days has finally gotten rid of the musty smell! I run it in one bedroom. It's quiet, it pulls tons of water out of the room and I can clearly feel the air getting dry. I hope it lasts a long time.

CADPXS Reply: Dear Webb, a fresh living environment is worth the investment.

The hose fits well and is easy to use.

I initially let this unit stand freely in our living space (it looks beautiful and clean, and small enough to not get in the way); it is a bit noisy (it has a compressor, a fan and a water pump) but is better than our air conditioned/ The stove is quiet. I use the hose that comes with the product, which is very suitable. So far this summer, the relative humidity of the entire basement has been maintained at about 55%.

CADPXS Reply: Dear Fisher, Thank you for your support and we will try our best to do better.

It removes water from the air at a nice clip.

I have purchased many dehumidifiers over the years. I use them 24/7/365 in my basement, which is not a particularly damp basement, but we are fanatics about keeping the humidity down there under 50% at all times. After my old unit was not removing moisture as well as it used to I made the switch to this unheard-of brand. It removes water from the air at a nice clip and is not terribly noisy. The big question with this and all units is: How long will it last? Nowadays, running it around the clock year round I seldom get more than 2-3 years out these. So, if this one can last at least that long my generous 5-star rating will rationally. If not, I will be sure to follow up immediately and advise against this one.

CADPXS Reply: Dear Alexander, Thank you for your 5-star rating. We can be sure that it will exceed your expectations.

This unit is so good!

I purchased this equipment for my non-climate controlled garage. I put it on a sturdy table and used a free drain hose to drain the water to the sewer. Now, I can easily store my music equipment and tools at the preset 40% humidity. In North Carolina, summer humidity is notorious. Before I bought this equipment, I could only stay in the garage for a few minutes. When the equipment is running, the air is much drier. This unit is very good for me because I forgot to set it up. When the humidity level is reached, it will automatically shut down and restart when needed.

CADPXS Reply: Dear Cox, We are glad that our equipment has helped you with your moisture problem.

High performance unit!

This dehumidifier has been replaced by a slightly smaller brand, which should be able to cope with the space it is located in. After installation, I let the previous machine run in an almost closed room for a while, but recently discovered that this device can be used to dehumidify the entire area. A few days later, for the first time, I felt that the floor was dry to the touch. It was cold before, and I couldn't tell whether it was cold or wet. I attribute it to the fact that the whole basement is cool. I never realized that the dehumidifier leaves too much moisture in the air. I have been running for nearly two months and I am very satisfied with it. Besides, I no longer have to worry about the humidity in the basement. I have a water sensor near the dehumidifier in case it leaks, but so do all other potential water sources in the basement.

CADPXS Reply: Dear Stewart, Thanks for your feedback, your satisfaction is our greatest pride.

This dehumidifier is excellent.

It is more compact than other dehumidifiers I’ve had in the past, however, it is much more powerful and operates much, much quieter. I use this in my 1100 square foot basement and it works perfectly at keeping the humidity at the correct level. The unit is very easy to operate and move around. Having the auto shut off and drainage modes are a plus.

Humidity control is very good!

Overall, this is a great machine and I recommend it if you have under 2000 sq.ft to dehumidify. With the recent heavy rains, my 1200 sq.ft apartment became too humid and began to smell musty. The dehumidifier was trivial to set up - just take it out of the box, plug it in and turn it on. It ran almost continuously for two days to wring the moisture out of the air, stopping only when the humidity up to standard. Now it cycles on and off and keeps the place comfortable. I put the machine in the second bedroom, so the noise level in the main living area and master bedroom is quite minimal. But even from there it keeps the entire apartment very comfortable.

Automatic drainage

This device is not that heavy, it must be powerful, and it's quiet. It is an easily accessible collection container with automatic drainage and washable filters that reduce bacteria, odors and other airborne particles. I particularly like its ability to reduce airborne bacteria and its amazing ability to dehumidify.

Easy to move!

It was easy to set up. Its wheels are easy to move, small in size and not too heavy.rnWhen I started it up, I was pleasantly surprised. This thing is much quieter than my last one. Way less noise. It looks a lot nicer too

It has my recommendation

I could feel the difference in the air inside the house after 30 mins of this being on And there's already water coming out of the hose. I was a little skeptical about paying that much for this, but I’m glad I did. It has lowered the humidity in my house, It doesn’t make much noise so that’s good.

It's Pretty Energy Efficient

I live in Florida and it gets very humid sometimes and even if the thermostat set for lover temperature you feel very uncomfortable because of humidity. This one is perfect for my living room that is an open space with a kitchen and dining room (about 1000 sq ft.) It reduced humidity super quickly and keep it on the level that I set it for. Works pretty quiet but the only thing Overall definitely recommend and it's much cheaper than well-known brands. My energy bill hasn't changed as well, so I think it's pretty energy efficient.

Great unit!

This works great. It’s quiet, and contains lots of great logic. Just make sure you size it correctly for proper operation. I’ve used this unit all summer as a whole house dehumidifier on the main floor of my house.
