بعد دقيقتين، هصب الميه في الفلتر.

Because Egyptian Arabic usually leaves out the subject pronoun when the verb already tells you who the subject is.

Here, هصب already means I will pour, so أنا is not necessary.

You could add أنا if you want emphasis or contrast:

• أنا هصب الميه في الفلتر = I will pour the water into the filter.

It is the Egyptian Arabic future marker. It gives the meaning of will or going to.

So:

• بصب = I pour / I am pouring
• هصب = I will pour

This is very common in Egyptian Arabic.

دقيقتين means two minutes.

It comes from the singular دقيقة = minute.
The ending -تين / -ين is the dual form, which is used for two.

So:

• دقيقة = one minute
• دقيقتين = two minutes
• دقايق = minutes

Because دقيقة is a feminine noun ending in ة, the ت shows up before the dual ending: دقيقتين.

Literally, it means after two minutes. In natural English, though, the idea is often in two minutes or two minutes from now.

So in this sentence, it means the speaker will do the action two minutes later.

This is different from talking about how long something takes. For example:

• بعد دقيقتين = two minutes from now / after two minutes
• في دقيقتين can mean within two minutes or in two minutes in a duration sense, depending on context

So بعد here is about time passing before the action happens.

Because this sentence is in Egyptian Arabic, not Modern Standard Arabic.

In everyday Egyptian speech, water is usually الميه.
In Modern Standard Arabic, it would be الماء.

You may also see the Egyptian word spelled in different informal ways, such as:

• الميه
• المية
• الميّه

They all represent the everyday Egyptian word for water.

In Arabic, في often covers meanings that English splits into in and into, especially after verbs like put, pour, or throw.

So:

• في الفلتر literally looks like in the filter
• but in this context it naturally means into the filter

The verb makes the movement clear, so في sounds normal here.

A natural pronunciation would be roughly:

baʿd daʔīʔtēn, haṣobb il-mayya fil-filter

A few useful notes:

• هصب is pronounced roughly ha-sobb
• الميه is pronounced roughly il-mayya
• في الفلتر is often said as fil-filter in connected speech

Also, فلتر is a loanword from English filter, which is very normal in Egyptian Arabic.

Yes. Egyptian Arabic is flexible here.

You can say:

• بعد دقيقتين، هصب الميه في الفلتر
• هصب الميه في الفلتر بعد دقيقتين

Both are natural.

Putting بعد دقيقتين first gives the time frame right away and slightly highlights it.

It is clearly Egyptian Arabic.

Clues include:

• هـ as the future marker
• الميه for water
• everyday colloquial spelling and phrasing

A more formal Modern Standard Arabic version would be something like:

بعد دقيقتين، سأصبّ الماء في المُرشِّح

But the original sentence is the natural colloquial Egyptian way to say it.
