Maybe can stay in friend or relative house for a few days if you’re fearful. I also just got my new house painted by nippon and staying at my parents place for abt a Week before moving in officially. Just to play safe.
Can consider getting a xiaomi air purifier with the green filter. It helps to remove formaldehyde. But for a peace of mind, consider staying somewhere else for at least 2 weeks.
Odourless may still have chemicals... I don't know what exactly is in the Nippon paint fumes but personally I'll take the baby and stay out of the house as much as possible.
Can take this chance to go for staycation and avoid the paint smell?
