Review on 🌬️ LBLVBNEWD 2 Pack True HEPA & 2 Pack Activated Carbon Replacement Filters Set Compatible with Levoit LV-PUR131, LV-PUR131S, LV-PUR131-RF Air Purifier - Enhanced Air Filtration System for Cleaner & Healthier Indoor Air by Brian Nicholas

Evil inside or new for air quality issues. Who I am? I'm the CEO of one of the most famous software companies for some industries because I invented the only embedded firmware (I'm not promoting my product here). So I know how things work, probably more than anyone here. This filter is slightly better than other third party filters on Amazon and the charcoal (carbon) it contains is not recycled which is possible for those nasty sellers. (I'm not saying they do, but it's still possible, so). Of course, you will smell bad for "the first 2-3 minutes" as you smell like new furniture or new electronics that just arrived. by manufacturers, like other 1 million goods worldwide will do the same. Therefore, the HCHO (formaldehyde, a chemical compound) level is high during those 2-3 minutes, after which it settles down to 0 readings. You have to plan these 2-3 minutes every day because all materials of manufacture produce this dirty thing naturally every day, as does ALL your furniture in your room. The reason why you should open the window for a little while every day. (if you do not have such a good air conditioner as a Levit + such a filter). TVOC also lands at 0 speed after 2-3 minutes. So this filter deals 0 damage after filtering the air. In auto mode it is close to HCHO 0 and TVOC 0 at speed 1, HCHO below 7, TVOC at speed 2 around 50, HCHO at 10, TVOC 100 (as expected) at speed 3, HCHO at 15-20, TVOC 150-200 (as expected), the higher the rate, the higher the displacement of CH2O from "production", so this is the expected rate. So what are these reviews? From a human point of view, this is one of the 3.1. an evil competitor smarter who bought a filter to deal more critical damage with a "Confirmed Purchase" icon. Don't worry, these evil sellers will slowly disappear as God won't allow it.2. someone either has a wrong nose or just had a bad day I guess. 3. Of course, some innocent paranoid people think that "you get what you paid for" but still risk their purchase, it is. IDK how to deal with it. Let them be part of the balance of the world. If the seller has a lot of such people, I suggest you double the price so they don't buy and get happy when they buy. (but I might look for other brands and compare if you really up the price). Is something wrong with my rating? You are safe? We can argue, provide our own data, and speak more scientifically.
