Why Consider the Shield 35M?
Crawl spaces and basements often hold onto humidity. Over time, persistent excess moisture can leave these areas feeling damp, create musty odors, and make stored items and building materials harder to keep dry.
A dedicated dehumidifier with continuous drainage can help keep humidity at your chosen level without constant attention. It is a moisture-management tool: it does not repair leaks, remove existing mold, or guarantee health outcomes, so address water intrusion at its source first.
Key Features
Continuous Gravity Drainage
Supports continuous drainage using the included gravity drain hose. An appropriate downward drainage route to a floor drain or other suitable outlet is required.
Moisture Removal Capacity
Rated at 35 pints/day under AHAM test conditions, and up to 70 pints/day under saturation conditions. Real-world removal depends on temperature and humidity.
Coverage Up to 1,000 Sq Ft
Manufacturer-rated for suitable crawl spaces and basements up to 1,000 square feet.
Simple Humidity Controls
Manual rotary control with 30%, 50% and 70% humidity settings, plus a continuous operation mode.
Automatic Defrost
Supports operation in cooler conditions, subject to manufacturer guidance. Auto-restart is also listed by Argendon.
Compact Construction
Compact build with ergonomic handles and adjustable leveling feet, designed for placement in crawl spaces and other suitable areas.
Limited Manufacturer Warranty
Argendon lists a 5-year limited warranty. Coverage is subject to Argendon's official warranty terms.
