I agree with other reviewers that the material feels thinner than the original filter. Zeolite with white spots looks like it was rarely applied. I didn't think it would do much but thought for $15 I'd give it a try. However, with my air quality monitor, I noticed a significant drop in VOCs in the air after the filter was turned on. Last week it was in the 600-900 ppb range (I used a non-charcoal/zeolite pre-filter) then after installing this pre-filter it dropped to around 70-200 ppb. I've also noticed that the readings go up when kids turn off the air filter. Overall, I'm *very* happy with my purchase. I've been considering $600 air purifiers designed to remove volatile organic compounds. Even if I have to replace that pre-filter monthly, it takes me 3 years to hit $600, and then these air purifiers have to replace their filters every 6-12 months anyway.
