Geomagnetic wall drying device: ATG reviews, prices and installation
06/11/2026Looking for reviews before buying a rising damp device is sensible. A testimonial, a polished case or a high price is not enough. Understand the product, its normal price and the support included before you decide.
Start with the source of the damp
These devices are intended for rising damp. Leaks, rain penetration and condensation require action suited to their cause. Photos and a phone call cannot replace an on-site investigation when one is needed. Establish an uncertain cause before buying.
Understand the ATE and ATG ranges
ATE is the electrically powered electromagnetic range. Select a model according to the building and stated coverage, then follow its installation and power instructions. The stated diameter is neither a radius nor an area in square metres.
Normal prices, without discounts
| Model | Stated diameter | Normal price |
|---|---|---|
| ATE LC15 | 15 m | 1 490 € |
| ATE LC30 | 30 m | 1 890 € |
| ATE LC30 PULSE | 30 m | 1 890 € |
| ATE MAX | 60 m | 2 290 € |
Reference public prices for the Humidistop range, excluding promotions. Check the product page for the applicable price and terms before ordering. Stated coverage diameters are model specifications, not a guarantee of results in every building.
What to check beyond the price
Compare the manufacturer’s identity, exact model, instructions, traceability, warranty terms and access to support. An attractive car body does not tell you about its engine; a device case is no different. A higher price does not prove better quality, and a lower price does not prove equivalent performance.
Practical strengths of Humidistop
Clearly identified models, visible prices, installation instructions and videos help you prepare your purchase. Customers outside France can obtain advice by email. The Humidistop range is manufactured in France and has a 10-year manufacturer warranty subject to its terms. Read the documents for your chosen model.
We advise customers in France by email and telephone. For customers outside France, advice is available by email only. We do not provide quotations or home diagnostic visits. Send your questions, building dimensions and available damp information. If an on-site investigation is needed, contact a suitable independent professional.
Customer reviews with clear context
Both clips feature the same Humidistop customer, who bought two ATE devices. He discusses his choice and customer support. These are not two independent reviews or comparative performance measurements. No exact model is attributed here.
The videos are in French and were published in 2021.
Clear commitments, without miracle promises
We do not promise to solve every damp problem or give one drying deadline for every building. Wall materials, thickness, water sources, ventilation and finishes matter. Record the initial condition, follow the instructions and monitor changes consistently. Being clear about limitations is part of a responsible purchase.
Questions before ordering
What damp source has been identified? Which model covers the intended zone? What does installation require? What does the warranty cover? Who answers after purchase? Get these answers before comparing prices alone.
