How effective are portable water filters?

I currently use one called waterdrop. You replace the water every 90 days.

The best water to drink is water that has been passed through a filtering process. Common and inexpensive filters are available, such as carbon filters like the ones Brita makes. The best filter is a reverse osmosis filter that puts the water through a multi-step process to remove microbes, pesticides, metals, and other toxins. 

So do these portable filters not actually remove metals & toxins? 

I don't have my own house my landlord is a social matrix sheep & I couldn't imagine convincing her to being allowed to play with the pipes & install a house filter like that or , unless it's really easy to work it out & I wouldn't brake something 

I think until I have my own place, , I will be drinking these portable filters... am I continually absorbing more metals & toxins?
