New Sub-Zero Fridge features NASA Technology to keep food fresh

The biggest problem of loading refrigerators with food is that the smells form each item mingles with the other. Besides this the next biggest hitch is that food turns stale pretty fast. Fridges are something that we can't do with or without, so best option is to keep improvising the functionality. That's exactly what the new Sub-Zero model does, it features a NASA designed filtration system. This system replenishes the air every 20 minutes thus eliminating bacteria, odors, and microscopic contaminants. The Built-In Fridge series features this filtration system and hopefully the pie won't smell like the Tuna anymore.
