i brought 3 sets - AUD$450 - of bedding covers (for our bed, baby bed and guest bed) from asthmatick website becoz i live in australia. so my baby can sometime sleep or play on our bed.
i think you can buy in asia website like sleepy or 3M. 3M most expensive, sleepy cheaper. and i think sleepy taiwan is cheaper then sleepy hk. they had sales a few weeks ago. but i think sleepy taiwan don't ship to hk... not sure. you have a look lor.
i wrap my baby's bed with plastic cover (plastic table sheet - no hole on surface) before i brought the bedding covers. becoz i need to search for cheaper price online (that's why i know all these brands) and they need time for delivery too.
避開麈蟎, use plastic bag to encase the mattress, tape it until there is no hole for dust mite to go in n out. cover the whole thing with bed cover on top. NO pillow!!!!
u need to buy dust mite proof bedding. e.g. sleepy/asthmatick
i brought asthmatick bed cover for my bb becoz of dust mite allergy.
