What is the recommended room size?
The chart below provides a quick guide to sizing a dehumidifier. The numbers are based on those provided by some manufucturers.
Keep in mind that these numbers are only a guide. There are other factors that affect the effectiveness of a dehumidifier, including the type (desiccant models tend to have lower listed capacities but are more effective in cooler conditions) and temperature of the environment.
| Environment | Room size | Room size | Room size | Room size | Room size |
| condition | 45 m² | 90 m² | 135 m² | 180 m² | 225 m² |
| Mild Damp | |||||
| 50% – 60% | 5.5 ltrs/day | 8 ltrs/day | 10ltrs/day | 12.5 ltrs/day | 14.5 ltrs/day |

| 60% – 70% | 6.5 ltrs/day | 9.5 ltrs/day | 12.5 ltrs/day | 15.5 ltrs/day | 18 ltrs/day |

What removal rate can I expect at 15c and 65RH or at another lower temperature?
The dehumidifying capacity of our Fresh 12L Portable Dehumidifier is 12L/ day is measured under the following circumstances of 30ºC and 80% RH.
As you can understand, unfortunately we are not able to provide an accurate answer according to your data (15ºC and 65% RH) but what can be mentioned is that each ºC and different RH% affects the unit’s performance. For example, in your specific case, in a lower temperature than 15ºC the performance of the unit will be reduced.
Moreover, the Fresh 12L Portable Dehumidifier is a compressor type dehumidifier with a great dehumidifying capacity.
How to set humidity level?
Can be set between 35 and 85% RH but so long as no other functions eg. Dryer, continuous or smart are running. The smart option will set humidity between 45 and 55% according to room temp. I have a lot of moisture from wet laundry and run it off mode and it keeps everything clear of condensation RH varies between 44 and 51% on silent mode continuously. Air temp 18degrees C.
Is it silent enough during sleeping next to bedside table?
It is not very quiet, I do not recommend that you leave the dehumidifier on overnight in your bedroom. The recommended humidity is between 40% and 60% if you leave it on while you sleep, you can get up in the morning with dry throat. The best place to put the dehumidifier in a house is the corridor with all the doors of the rooms open for 24 hours if it is the first time you use it in your house.
How to clean the filter?
I this product is a brand new one in our Dehumidifiers family. So, this unit’s filter is new and you are able to keep using it for quite some time, after cleaning it up following the instructions provided in the manual and below:
- “Always clean the air filter every 2 weeks. If the unit operates in a dusty atmosphere clean the air filter more often.
- Remove the air filter from the back side of the unit and clean it with a vacuum cleaner.
- If the air filter is very dirty, you can wash it in warm water (never use hot or soapy water). Make sure that the air filter is dry and refitted correctly. Do not bend the filter and ensure it is fitted before operating the unit.”.
Would 1 unit be sufficient for a 3 bedroom house?
We have had ours for about 2 weeks and are pleased with the sheer amount of water that it’s collecting. We have a rambling house with a 5 bedrooms with a big condensation problem and black mould and it seems to be doing ok. Like you we considered getting 2 but decided to try one for now. It’s very powerful. We wheel it from room to room, a different one each day and it seems to be working well. At the start there will be a lot of water but the amount pulled out will gradually decrease. So maybe no need to buy 2 at the start.
