The Waterpik 100 is a sleek, affordable dental water jet system by a trusted brand. Although the highest setting (#10 at 90psi) is a little strong for me, I like having the option in case there is a stubborn piece of food or something that just won't budge with lower settings. Neither of the other dental water jets below offer that much pressure.

Both the Waterpik 100 and the Conair Interplak system have two year warranties, a year longer than the Hydro Floss system, and both include similar tip attachments. However, after testing both systems we felt the Waterpik 100 felt better made and we enjoyed the additional water pressure settings. The Waterpik is also a much better looking system, but of course that is a matter of personal preference and opinion. You can decide for yourself from the pictures. With that said, the Conair Interplak dental water jet is about $15 cheaper than the Waterpik, so that might factor in. Both are great systems and both are less than half the cost of the Hydro Floss option.

The Hydro Floss Oral Irrigator is a top-notch dental jet system overall, but it falls short of providing enough value to account for the more than double price-point difference. It has fewer pressure settings than the Waterpik 100, and less PSI. They probably want to play it safe with the PSI but, like I said, I enjoy having the option. The reason for the price increase is for the Hydromagnetics concept, but I didn't get a good idea from the website or instructions as to what that meant exactly. In terms of the actual water jet, it didn't feel any different. And since they offer a year less warranty coverage than the other two units, I can't imagine they have too much confidence in the quality of their system.

BOTTOM LINE: All three are good dental water jet systems, but the Hydro Floss oral irrigator isn't worth twice the price of the Waterpik 100. The Conair Interplak WJ7B is a great buy at $45 but I would be willing to pay an extra $15 for the additional features and pressure offered by the Waterpik 100. That is why they get our Editor's Pick.
