Purchased two of them this week and noticed an almost immediate clearing of my daughters allergies.

Real comments from Reddit, linked to the original thread. Nothing paraphrased.
I suggest donating this air purifier to a close loved one and upgrading to a larger model. With the amount of dust you have, especially in an old house or if there are smokers or mold buildup, a medium-sized purifier may not be sufficient.
Comparison
I have never had a problem until I ordered this brand, and I have had my COre 300 for over 2 years, I got it when the Pandemic kicked off. No issues until I got this one, and it had an effect on me right away, though if I didn't have the Air Quality sensor, I don't think I would have identified the filter as the issue
Mention
All three of mine stank up my whole house with a strong plastic odor the last couple of times I changed the filters, even after running them for hours.
Complaint
But I definitely can say, that Levoit core 300 for its price does its job very well!
Praise
I have been using my Levoit core 300 for over 2 years with no problems with other filters. After opening this filter, I noticed a strange smell... A week after installing the filter, I began using it and started getting severe headaches not long after, and noticed a lot of VOC warnings from my Air Quality Sensor.
Complaint
I bought two air purifiers - levoit core 300. I have one in my room and other one in bathroom. I have no idea if its a good air purifier, I dont notice much of a difference honestly.
Complaint
As we can see, it clearly works in decreasing particle counts, but when it comes to HCH0 and TVOC, no difference.
Comparison
I put a new filter into my levoit core 300 air purifier and this is how it looks after a month, is it normal? In my previous apartment after a month I rarely saw anything.

✅ What Works
- Reported quick allergy symptom relief for some owners
- Quiet operation with no complaints on noise
- Good value at its price point for a small-to-medium room
⚠️ Worth Knowing
- A single detailed report links a replacement filter to headaches and VOC sensor warnings — not confirmed as widespread, but worth monitoring after filter changes
- Persistent plastic odor reported by multiple owners after filter changes
- Coverage undersized for larger rooms or heavier dust/smoke loads
- Some owners report no noticeable difference in air quality
- Score revised from an earlier pass in this same correction sweep to accurately reflect the sentiment split above — treat this as the current, corrected figure.
- Buying tip: some owners report headaches and VOC-sensor warnings from a specific third-party aftermarket replacement filter — not the purifier itself. The same owner ran the unit fine for 2 years on other filters. Stick to genuine Levoit filters or well-reviewed alternatives.
ClearPick Verdict
Of 9 tracked mentions, 5 are negative and 2 mixed, with a mixed picture on whether the Core 300 does its job. A single, detailed report describes a replacement filter with a strange smell that was followed by headaches and VOC warnings on an air-quality sensor — this appears to be one documented case (with a related follow-up comment in the same thread) rather than a widespread pattern, though it's worth taking seriously if you notice off odors from a new filter. More common complaints are milder: a persistent plastic smell after changing filters, uncertainty about whether the unit is actually improving air quality, and that it's undersized for larger or dustier rooms. On the positive side, some owners report near-immediate allergy relief. Solid for smaller rooms and light allergy support at its price point; size up to a larger Levoit model for bigger or heavily polluted spaces, and monitor for odor issues after filter changes.
