Perfect fit & I like the pre-filter also. That was new to me.

These filters fit our Morento air purifier
We have a Morento air purifier model HY4866-WF. These filters fit it perfectly. These are not the Morento brand, but an after market option. The air purifier does not have a sensor to determine filters being installed, it only keeps track of time being installed if the filter replacement indicator is reset when the filters are exchanged.
It is hard to rate the efficiency of these filters with only a couple of weeks of use, but for now, the most important feature for me is that the dimensions actually fit the device and the airflow appears to not have been affected.
These 4 filters should give us a year of air filtering (the recommendation is to replace them every six months, and the purifier uses two simultaneously – one at each side)

Great deal for great Hepa Replacement filters
I purchased the Morento Hepa air purifier which uses two Hepa filters on each side of the unit’s intake vents I purchased this model for my bedroom as dust particles and dust mites effect my breathing and since suffering a massive hemorrhagic stroke in April of 2023 I need to live in a very sanitary environment. The ad for the purifier said the filters last 5-6 months my first set which came with the product lasted a little over 5 months . So I had a choice on the Amazon APP to purchase authentic Morento replacement Hepa filters for two filters at $32.00 or they offer aftermarket identical Hepa Filters as highly rated as the factory ones in a set of 4 filters for $27.00 they feel and look exactly like the original ones I received when I first received the air purifier but for about $14.00 for two Hepa filters that will hopefully last 5-6 months I’m extremely happy with that deal I just hope these filters last as long as the original factory ones so far so good the air purifier with filters on both sides has made a huge change in my breathing and sleep . I would recommend the Morento two sided Hepa air purifier to anyone that wants clean air to breath in their home . I plan on buying 2 more units for my home I’m just not sure if they will be the Morento units when not on sale are about $200.00 each or I really want the Shark never change Hepa filter air purifier which with tax is about $300.00 but when my cost to change the filters is only $14.00 every 5-6 months and they put the air purifier on sale whether it’s a prime day or Black Friday for $103.00 I truly feel it’s a great deal for something that has definitely made my life much more comfortable. There were some bad reviews very few mostly about the power cord connection or units with defective power chord connections it’s 6 months and I haven’t had an issue also the reviews in regards to the power chord connections all said they got hold of the manufacturers customer service department which addressed the issue in a timely and positive reaction .
