uv steriliser

Yes. They can all be UV sterilised. The lifespan of these pump parts and bottles are probably a couple of months depending on usage. You will need to check for tears, discolouration, stains and sticky feel etc and replace them if needed.

Best to avoid uv sterilising PP bottles, as they age very fast and may leech chemicals. Philips avent only has PP bottles, bets to use PPSU bottles https://shopee.sg/product/242594539/5732034154?smtt=0.0.9
