Buying Guide
What size should you choose for a 70-pint unit?
Choose based on space size, ceiling height, and moisture level. For spaces up to 4500 sq ft, a 70-pint model is typically sufficient. For larger or more humid spaces, consider units with higher airflow or additional drainage options to maintain steady humidity levels.
What drainage options matter?
Continuous drainage with a pump is convenient for basements and crawl spaces. Gravity drainage requires a nearby drain but reduces the need to monitor the tank. Consider how your space is plumbed and whether you want to avoid manual tank emptying.
How important are extra features?
Intelligent humidistats help maintain precise humidity, while modes like Drying or Ionizer can tailor performance. Noise level matters in living areas; look for models claiming quiet operation under typical conditions.
Energy efficiency and running costs
ENERGY STAR-rated models save energy and reduce long-term costs. Compare CFM, humidity range, and defrost features to understand real-world efficiency in cold or damp environments.
Maintenance considerations
Look for accessible filters, easy drainage connections, and durable casings. A pump drainage option is beneficial for high-position drains or unattended operation in basements.
Choosing by use case
- Basements and large rooms: prioritize 4500 sq ft coverage and multiple drainage options.
- Crawl spaces and commercial spaces: pick units with higher airflow and robust construction.
- Quiet spaces or bedrooms: favor models with low dB ratings and sleep modes.
