This is because the web site is giving you no information that pertains to efficiency. You would need to go to the websites of the manufacturers and find the model you want and look at their information on efficiency.
If you have gone to the trouble of making your house tight enough that it feels stuffy, you have done a good job of reducing air infiltration... not always so easy to do. So you should seek out (or make) a high efficiency HRV.
If you can't find efficiency information, you probably shouldn't buy the unit. Efficiency information is something that manufacturers are proud of, if their HRV is a high efficiency unit.
