Query: Does not last much past warranty period

I have had 4 of these now. I found it to boil water quite quickly. I also had the problem with one of them that the filter would fall out, but was able to pop it back in easily.The main issue is that only one has last beyond 2 years. Usage on the longer lasting one is probably 1-2 times per day, and on the ones that did not last, maybe a bit less.
