Open Box Aiusevo AS300 Home Dehumidifier

A musty basement smell, beads of water on the inside of your windows, towels that never quite dry: these are classic signs of too much moisture indoors. The Aiusevo AS300 dehumidifier is a compact home unit designed to pull that excess moisture out of the air and help keep a room at a more comfortable humidity level. This open-box unit costs $109.99 and comes with its user manual and a drain hose.

Where the Aiusevo AS300 dehumidifier fits in a Canadian home

Humidity problems here tend to follow the seasons. In summer, sticky air settles into basements and below-grade rooms. In winter, cooking, hot showers and indoor drying racks add moisture that ends up as condensation on cold window glass. The AS300 is aimed at everyday spaces like these:

• a finished or unfinished basement that smells closed-in;
• a bathroom without a strong exhaust fan;
• a bedroom or home office where the air feels heavy;
• a condo or apartment where the windows fog up on cold mornings.

Features on the AS300

A clear digital display

The control screen on the front lets you check the unit’s settings and status at a glance.

A drain hose for long runs

Emptying collected water by hand gets old fast in a damp basement, so the included hose lets you route it away continuously instead. Hoses like this usually rely on gravity, so plan for a floor drain, sump or utility sink lower than the outlet, and follow the manual when connecting it.

A small footprint

The plain white cabinet is small enough to sit in a corner without taking over the room. Before ordering, check where it will go, make sure there’s an outlet nearby, and read the manual for placement guidance.

Figures we don’t have yet

Our product sheet doesn’t list a daily moisture-removal rating (pints or litres per day), a recommended room size, the tank capacity or a noise level. Ask our team for exact figures before you buy, especially if you’re sizing a unit for a large or very wet basement. A small hygrometer is also handy for tracking how a room changes over time; a common indoor target is roughly 30 to 50 percent relative humidity.

A note on mould

Mould needs damp conditions to grow, and a dehumidifier can help reduce that dampness. It won’t remove mould that’s already there, and we can’t promise it will prevent mould in every home. Clean any visible growth, fix leaks at the source, and call a professional if the problem is large or keeps coming back.

AS300 or TZ02?

We also carry the open-box TZ02 dehumidifier with laundry drying mode at the same price. Here’s how they compare on our product sheets:

Choose the AS300 for a compact unit that mostly stays in one room. Choose the TZ02 if you dry laundry indoors or want to roll it between rooms.

Open-box details, warranty and shipping

Open box means the original box has been opened, so this dehumidifier isn’t sealed-new. Each unit is inspected and tested first, as our open box grading guide explains. It’s covered by our 90-day limited warranty, and you have 30 days to return it in the condition you received it. At $109.99 it ships free across Canada; our shipping policy lists delivery times.
