Another US brand, Honeywell, is considered to be Holmes’ main competitor. Both brands provide affordable, good performance products in a wide variety of designs.

They both have regular sales and coupons, with Holmes humidifier coupons appearing more regularly. Holmes offers more frequent discounts than Aprilaire, but Aprilaire is more well-known than Holmes.

Holmes vs. Crane

Crane is known to provide a wide range of humidifiers for both children and adults in different colors and room size options. Their selection of humidifiers is more comprehensive than Holmes’ but also more expensive overall. If you want more basic and affordable models, choose Holmes.

Holmes vs. Vicks

Vicks, as a brand, typically focus on healing illness and sinus issues, and their humidifier range is no different. Both Holmes and Vicks’ range of humidifiers are available for similar prices and comes in cold, hot, and ultrasonic varieties while having a smaller range.

Fixing Common Humidifier Problems

The humidifier is not steaming properly

This is most likely due to mineral buildup in the tank or near the spout. Cleaning it regularly and soaking in a water and vinegar solution should remedy this issue.

The tank is leaking water

If your Holmes humidifier leaks water, it is often due to the tank not being installed properly or being cracked in some way. Try readjusting the tank and letting it run for a bit. If the leaking continues, inspect it for damage and request a replacement from Holmes.

The humidifier is really noisy

If your humidifier is making a lot of noise, that is usually down to loose parts. Carefully unplug the unit and empty the tank before taking the model apart and tightening everything carefully. Pay particular attention to the screws, shaft, and mounting fasteners.

The humidifier smells bad

For foul odors, we recommend thoroughly cleaning the unit and cleaning the evaporator belt pads and fan blades. Look for mold or limescale buildup in particular.
