I repeatedly purchased this items to replace HEPA filter for my house. Nice quality and cost effective. Fitting is perfect.

I change every 2 months. I’m happy with them. My air quality is improved.

I use these 16x25x1 filters for the Trane AC/HVAC system at my rental property and have been really happy with them. They fit perfectly, and the difference in quality compared with the cheaper filters I was using before is obvious as soon as you take one out of the package. The frame feels sturdy and the filter media itself looks much more substantial. I’ve also noticed that they do a much better job of keeping the air feeling clean. The MERV 13 rating is especially nice because it can capture much finer particles, including a lot of the particles found in smoke, as well as very small airborne particles that lower-rated filters may miss. Overall, these feel like a significant upgrade over basic HVAC filters. Great fit, noticeably better construction, and good filtration for a rental property where I want to keep the indoor air as clean as reasonably possible for my tenants.

These are perfect, and they are way cheaper than getting them from Lowes or home depot

Correct size and fit. Great airflow. Oder reduction.

Minimum you should get is MERV13 rating. I've bought these twice. Good product.

Works so far. My area was heavy in smoke a lot this summer due to wild fires.

I ordered a quantity of 4 - 16x25x4" filters which were a better price than the Filtrete filters I've previously used.. These filters are certainly equal in quality... Will certainly order them again..

Great

As you can see in the photos, the filter is 4” longer on the one side of my 20” box fan. I simply cut a piece of cardboard for that section and taped off everything to a good air seal. I keep the fan going in my back bedroom to cut down on the noise. I also operate it from 7 pm to 7 am on low. These are the lowest hydro rate times. I keep the furnace air vent wide open in that room and the door wide open too for good air circulation in my 850 square foot house. There is hardly any dust on my floors or in my house now. I used the big fan on high during bathroom renovations last month and little dust settlement. I can see I will have to change this filter at the three month mark because of the renovations. But the next one, I hope can extend for six months before replacement. Yes, the MERV 13 filters are expensive, but in these pandemic times, and me being 69 with health problems; my goal is the best air quality. I am quite happy with this simple portable solution. And hey, the 20” fan was $30.00 at Canadian Tire store. I saw an identical fan on Kijijii for $10.00. Fans are dirt cheap, but really do the air circulation job well for the filter operations.

Great filters AAA plusfor catch the dust .

My apartment building recently changed the type of filters they use to save costs. They went from a brand name MERV 11 filter to a no-name MERV 6 filter. I immediately noticed a difference in my air quality and the amount of dust in my apartment. As I have COPD and am on oxygen this was not good. I did some research and found out the vast differences in MERV ratings and decided I need to purchase my own filters for the sake of my lungs. I found these MERV 13 at a great price so ordered them looking forward to breathing better soon. Unfortunately they sent the wrong size! I contacted Customer Service who were very friendly and professionally and immediately shipped out the correct size. I think they put a rush on the shipping as I had the correct filters in just a couple of days. I can tell the difference in the air quality already! I'm am looking forward to dusting so I can see how much less dust accumulates less quickly. These MERV 13 filters trap just about everything - they are the highest rated for residential use. Not even the particles from the summer wildfires are going to get through. Very happy with my purchase (so are my lungs!) and will be buying from this awesome seller again.
