Learn how to install and place the DREO aroma pad for 338/338S air purifiers, avoid common scent mistakes, and get steady, even fragrance without overdoing it.
Quick answer
Install the aroma pad in the designated slot of your DREO 338/338S air purifier, add only a few drops of essential oil, and start on a low fan speed. Check the pad after the first day and adjust the amount or placement before adding more oil.
Why less oil gives you better control
A little essential oil goes a long way in a moving airstream. Start with two or three drops, run the purifier on low for an hour, and then judge the strength in the room. If the scent is too faint, add one drop at a time rather than soaking the pad. Over-oiling can make the fragrance sharp and leave a residue that is harder to clean.
Placement matters more than you think
The aroma pad belongs in the purifier's intended pad holder, not taped over the outlet or dropped loose inside the housing. Placing it correctly lets air pass through the pad evenly. Keep the purifier at least a few feet from walls and curtains so the scented air can circulate instead of pooling in one corner.
When to skip the scent pad
If anyone in the home has asthma, fragrance sensitivity, or a respiratory condition, check with them before adding essential oils to the air. Pets and small children also react differently to concentrated scents. In those cases, run the purifier without the aroma pad and rely on filtration alone.
Step-by-step aroma pad setup
- Confirm your model and pad: Check that your purifier is a DREO 338 or 338S in Black or White (DR-HAP008/DR-HAP008S). The aroma pad is made for these models. If you have a different purifier, do not cut or bend the pad to fit. A model mismatch is the most common reason a pad sits loosely or blocks airflow.
- Power down and locate the pad holder: Turn off and unplug the purifier before opening any cover. Find the small pad tray or slot designed for the aroma pad, usually near the filter housing or outlet. Do not place the pad directly against the filter media. If you cannot find a dedicated holder, stop and check your manual rather than improvising.
- Add oil sparingly: Place the pad in the holder first, then add two or three drops of essential oil across the surface. Avoid pouring oil directly into the purifier or onto the filter. Wait a minute for the oil to spread before closing the cover. More oil does not mean longer scent life; it usually means a stronger first hour and a faster fade.
- Run on low and assess: Plug the purifier back in and run it on the lowest fan speed for about an hour. Walk into the room from outside to judge the scent level accurately. If it is too strong, remove the pad and let it air out; if it is too weak, add one drop. Judging scent from inside the room all day makes you nose-blind to the actual level.
- Check and refresh the pad: After the first day, inspect the pad for dryness or residue. Reapply one or two drops only when the scent fades. Replace the pad when it becomes stiff, discolored, or holds oil unevenly. A saturated pad can restrict airflow, so replace rather than over-soak.
