Quel est le taux d'humidité idéal dans une maison ?

Le taux d'humidité relative idéal se situe entre 40 et 60 % selon l'ADEME et l'OMS. En dessous de 30 %, l'air est trop sec ; au-dessus de 70 %, les moisissures et acariens prolifèrent.

Combien coûte un traitement contre l'humidité en 2026 ?

Comptez 80 à 150 €/ml pour des injections de résine contre les remontées capillaires, 1 500 à 4 000 € pour une VMC double flux, 150 à 250 €/ml pour un drainage périphérique et 200 à 500 €/m² pour un cuvelage de cave.

Comment savoir d'où vient l'humidité dans une maison ?

Un diagnostic professionnel (hygrométrie, caméra thermique, test au carbure) permet d'identifier la cause : remontées capillaires (bas des murs), condensation (fenêtres, ponts thermiques), infiltrations (toiture, façade) ou fuite. Le diagnostic est gratuit chez les experts ZeroHumi.

Quels sont les risques de l'humidité sur la santé ?

Selon l'OMS, l'humidité excessive favorise asthme, allergies, rhinites, bronchites chroniques et infections respiratoires. Les enfants, personnes âgées et immunodéprimés y sont particulièrement sensibles.

Mon propriétaire doit-il traiter l'humidité dans mon logement ?

Oui. La loi du 6 juillet 1989 (article 6) impose au bailleur de fournir un logement décent, exempt d'humidité pathologique. En cas de manquement, le locataire peut saisir la Commission départementale de conciliation ou le tribunal.

Frequently Asked Questions

Is the COMFEE 20L suitable for a basement?

Yes, up to 70 m² provided the temperature remains above 12 °C. In cold basements (<10 °C), prefer a low-temperature compressor model or a desiccant dehumidifier.

How does the WiFi application work?

The COMFEE Home app (iOS/Android) connects via 2.4 GHz WiFi and allows you to program, track humidity in real-time, and receive an alert when the tank is full.

What is the actual power consumption?

At 370 W and 12 h/day, count ~13-15 € per month (regulated EDF 2026 tariff). In auto mode with hygrostat, consumption drops by 30-40% once the target is reached.

Comfee MDDF-20DEN7-WF or Pro Breeze 20L?

The COMFEE is more connected (WiFi/app) and quieter (45 vs 48 dB). The Pro Breeze has a larger tank (5 L) and better customer feedback for basements. For bedroom/living room use, COMFEE. For basement/sub-basement, Pro Breeze.

Where to buy at the best price?

To date, Amazon offers the best rate (170 € delivered) with 30-day free returns. Avoid unverified third-party sellers: COMFEE does not have direct after-sales service in France.
