Its manual specifies approximately 500 ml of water collection per day at 30°C (86°F) and 80% relative humidity, with a 1,500 ml tank. Those are manufacturer figures under stated conditions—not independent test results or a guarantee of how much it will collect in your room. The available evidence supports a review of its design, specifications and practical limits, but not claims about measured noise, energy use or real-world performance.
What is the Pro Breeze PB-03?
The PB-03 is a small dehumidifier that uses a thermo-electric Peltier module instead of a compressor. Its 2017-copyright instruction manual describes the design as “lightweight and quiet” and says it is intended for small, poorly ventilated rooms, wardrobes, cabinets and storage rooms. These are the manufacturer’s descriptions, not independently verified findings or a tested room-size recommendation. The PB-03 instruction manual

There is also a regional distinction to keep in mind: a Pro Breeze US registration page lists a PB-03-US-FBA variant and associates it with a 2,200-cubic-foot (250-square-foot) descriptor. That listing does not establish that every PB-03 has identical specifications, nor that this variant is currently available for sale. Pro Breeze US registration page

| Specification | Manufacturer-stated detail | How to interpret it |
|---|---|---|
| Water collection | Approximately 500 ml (18 oz) per day at 30°C (86°F) and 80% relative humidity | This is a condition-specific figure. The manual does not establish the collection rate in cooler or drier conditions. |
| Water tank | Maximum capacity 1,500 ml (52 oz) | Tank size is separate from the daily collection figure; it does not indicate how much water the unit will collect in a particular room. |
| Moisture-removal technology | Thermo-electric Peltier module; compressor-free design | The manual identifies the technology but provides no independent comparison with compressor-based models. |
| Fan motor | Brushless motor | The specification does not establish measured noise or electricity use. |
| Power input | AC 100–240 V, as stated in the multilingual manual | Check the manual and rating label for the specific regional unit before assessing mains compatibility or adapters. |
| Space descriptor | 2,200 ft³ appears in the model/manual naming; the US registration page lists 2,200 ft³ (250 sq ft) for PB-03-US-FBA | These descriptors are not a verified room-size recommendation or proof that regional versions are identical. |
How much water does the PB-03 collect per day?
Pro Breeze states approximately 500 ml (18 oz) per day when the air is at 30°C (86°F) and 80% relative humidity. Treat that as a manufacturer-stated rate under warm, humid conditions, not as a typical result for every home. The manual does not give an independently tested collection rate for cooler or drier conditions.
The manual gives the tank a maximum capacity of 1,500 ml (52 oz). Taken together, these figures suggest that emptying frequency depends on how much moisture the unit actually collects and how long it runs; they do not establish a fixed number of days between emptying.

What size room is the PB-03 for?
The PB-03 manual describes use in small, poorly ventilated rooms and spaces such as wardrobes, cabinets and storage rooms. The 2,200-cubic-foot figure appears in the model/manual naming, while the manufacturer’s US registration page associates 2,200 cubic feet (250 square feet) with the PB-03-US-FBA variant. Neither source provides a documented test showing that the unit can control humidity across a room of that size.
Use the space description as manufacturer guidance, not a performance guarantee. A large, open or especially damp room may place different demands on a compact unit than an enclosed storage area; the available specifications do not quantify how the PB-03 performs in either case.

Is the Pro Breeze PB-03 quiet?
The manual says Peltier technology makes the appliance “lightweight and quiet.” That is the manufacturer’s characterization. The available sources provide no measured sound level, test method or comparison with other dehumidifiers, so they do not establish how loud the PB-03 will seem in a particular room.

What this review can—and cannot—establish
The manuals establish the manufacturer’s stated design, operating guidance and specifications. The available sources do not provide independent measurements of extraction, noise, electricity use, durability or performance in a defined room. As a result, they do not support calling the PB-03 demonstrably energy-efficient, especially quiet, long-lasting or more effective than another model.

For a meaningful comparison with another dehumidifier, look for extraction figures tested under the same temperature and humidity, a clearly stated tank capacity, and room-size guidance backed by a defined method. Noise and electricity-use comparisons also require measurements made under consistent conditions; the PB-03 specifications cited here do not supply those results.
